8 Detailed Description
8.1 Overview
The OPAx863 devices are low-power, 50‑MHz, rail-to-rail input and output (RRIO), bipolar, voltage-feedback
operational amplifiers with a voltage noise density of 5.9 nV/√Hz and 1/f noise corner at 25 Hz. The OPAx863
work with a wide-supply voltage range of 2.7 V to 12.6 V, and consume only 700 μA quiescent current. The
OPAx863 operate with a 2.7 V supply, are RRIO capable, consume low-power, and offer a power-down mode,
which makes them great amplifiers for 3.3‑V or lower-voltage applications that require excellent ac performance.
The main and auxiliary input stages of the amplifier are matched for gain bandwidth product (GBW), noise, and
offset voltage and designed for applications that require wide dynamic input range and good SNR.
The device includes an overload power limit feature which limits the increase in quiescent current with over-
driven and saturated outputs to either of the supply rails. For more details of this overload power limit feature,
see Section 8.3.2.1. The amplifier's output is protected against short-circuit fault conditions.
The OPAx863 feature a power-down mode (PD) with a PD quiescent current of 1.5 µA (maximum) with a 3‑V
supply, with turn-on and turn-off time within less than 6.5 µs.

8.3 Feature Description


8.3.1 Input Stage
The OPAx863 include a rail-to-rail input stage. The main stage differential pair using PNP bipolar transistors
operates for common-mode input voltages from VS– – 0.2 V to VS+ – 1.6 V. The amplifier inputs transition into
the auxiliary stage using NPN transistors for common-mode input voltages from VS+ – 1.6 V till VS+ + 0.2 V. The
PNP and NPN input stages offer a gain-bandwidth product of 50 MHz and a voltage noise density of 6.3 nV/√Hz.
The offset voltage for the two input stages is matched to lie within the device specifications. The auxiliary NPN
input stage does not use the slew-boost circuit during large-signal transient response. The input bias current for
the PNP and NPN input stages is opposite in polarity, which adds an additional offset based on the values of
the gain-setting and feedback resistors. A common-mode input voltage transition between these input stages
causes a crossover distortion that must be considered in high-frequency applications requiring excellent linearity.
Limit the common-mode input voltage to VS+ – 1.6 V (maximum) for main-stage operation across process and
ambient temperature.
The OPAx863 are bipolar amplifiers; therefore, the two inputs are protected with antiparallel back-to-back diodes
between the inputs, which limits the maximum input differential voltage to 1 V. The amplifier is slew limited,
and the two inputs are pulled apart up to 1 V when the antiparallel diodes begin to conduct in very fast input
or output transient conditions. Make sure to use gain-setting and feedback resistors large enough to limit the
current through these diodes in such conditions.
8.3.2 Output Stage
The OPAx863 feature a rail-to-rail output stage with possible signal swing from VS– + 0.2 V to VS+ – 0.2 V.
Violating the output headroom of either supply causes output signal clipping and introduces distortion.
The OPAx863 integrate an output short-circuit protection circuit that makes the device rugged for use in real-
world applications.
8.3.2.1 Overload Power Limit
The OPAx863 include overload power limiting that limits the increase in device quiescent current with output
saturated to either of the supplies. Typically, when an amplifier output saturates, the two inputs are pulled
apart, which can enable the slew-boost circuit. The input differential voltage is an error voltage in negative
feedback that the amplifier core nullifies by engaging the slew-boost circuit and driving the output stage deeper
into saturation. After the input to an amplifier attains a value large enough to saturate the output, any further
increase in this input excitation results in a finite input differential voltage. As the output stage transistor is
pushed deeper into saturation, the base-to-collector current gain (hFE) drops with an increase in the base and
collector current, and an increase in the device quiescent current. This increase in quiescent current can cause
a catastrophic failure in multichannel, high-gain, high-density front-end designs, and reduce operating lifetime in
portable, battery-powered systems.
The OPAx863 overload power limiting includes an intelligent output saturation-detection circuit that limits the
device quiescent current to 2.2-mA per channel under dc overload conditions. This increase in quiescent current
is smaller with ac input or output and output saturation duration for only a fraction of the overall signal time
period. Table 8-1 compares the increase in quiescent current with 50‑mV input overdrive for OPAx863 devices
and other voltage-feedback amplifiers without overload power limit.

8.3.3 ESD Protection


As Figure 8-1 shows, all device pins are protected with internal ESD protection diodes to the power supplies.
These diodes provide moderate protection to input overdrive voltages greater than the supplies. The protection
diodes typically support 10-mA continuous input and output currents. Use series current limiting resistors if input
voltages exceeding the supply voltages occur at the amplifier inputs, which makes sure that the current through
the ESD diodes remains within the rated value. OPAx863 is a bipolar amplifier; therefore, the two inputs are
protected with antiparallel, back-to-back diodes between the inputs that limits the maximum input differential
voltage to approximately 1 V. Make sure to use gain-setting and feedback resistors large enough to limit the
current through these diodes in fast slewing conditions.

8.4 Device Functional Modes


8.4.1 Power-Down Mode
The OPAx863 includes a power-down mode for low-power standby operation with a quiescent current of only
1.5 μA (maximum) with a 3-V supply and high output impedance. Many low-power systems are active for only a
small time interval when the parameters of interest are measured and remain in low-power standby mode for a
majority of the time and an overall small average power consumption. The OPAx863 enables such a low-power
operation with quick turn-on within less than 6.5 μs. See the Electrical Characteristics tables for power-down pin
control thresholds.
Always drive PD pin to avoid false triggering and oscillations. If power-down mode is not used, then connect the
PD pin to VS+. For applications that need power-down mode, use an external pull-up resistor from the PD pin to
VS+ (driven with an open-collector power-down control logic).

Figure 8-2 shows the choice of value of the pull-up resistor RPU, which impacts the current consumption in
power-down mode. Using a large RPU reduces power consumption, but increases the noise at the PD pin, which
can cause the amplifier to power down. A 1‑nF capacitor can be used in parallel with RPU to avoid coupling of
external noise and false triggering. For the case of the PD pin driven to VS-, the IPU current through RPU is given

9 Application and Implementation


Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.

9.1 Application Information


The OPAx863 are classic voltage-feedback amplifiers with two high-impedance inputs and a low-impedance
output. These devices have a GBW of 50 MHz, 5.9 nV/√Hz of noise, RRIO capability, and precision performance
consuming only 700 µA quiescent current per channel These features make the OPAx863 an excellent choice
for use in low-side current sensing, ADC input driver, and reference buffering with fast settling, buffers, high
gain and filter circuits. The overload power limit makes the OPAx863 truly low-power in high-gain, multichannel
systems limiting any increase in quiescent current during output overload conditions.
9.2 Typical Applications
9.2.1 Low-Side Current Sensing
Power converters use current-mode feedback control for excellent transient response and multiphase load
sharing. Inverter stages control the phase currents for torque control in motor drives. As a result of the simplicity
and low-cost, many of these topologies use difference-amplifier-based, low-side current sensing. Figure 9-1
shows the use of the OPAx863 in a difference amplifier circuit for low-side current sensing.

9.2.1.2 Detailed Design Procedure


In a difference amplifier circuit, the output voltage is given by:

4(
81 = + 4 + 84'(
4) 5* 5* (2)

For lowest system noise, small values of RF and RG are preferred. The smallest value of RG is limited by the
input transient voltage (10 V here) seen by the circuit, and is given by:

8+0(I=T .) F 8& F 85
4) =
+&(I=T .) (3)

Where,
• VIN(maximum) is the maximum input transient voltage seen by the circuit.
• VD is the forward voltage drop of ESD diodes at the amplifier input.
• ID(maximum) is the maximum current rating of the ESD diodes at the amplifier input.
For a difference amplifier gain of 20 V/V, an RF of 12 kΩ and RG of 600 Ω are used. With a clock frequency of 40
MHz and the ADS7056 sampling at 1 MSPS, the available acquisition time for amplifier output settling is 550 ns.
Figure 9-2 shows the simulation results for the circuit in Figure 9-1. The worst-case peak-to-peak input transient
condition is simulated. The output of the OPAx863 device settles to within 0.1% accuracy within 543 ns. If using
a slower clock frequency with the ADC is desired, then the acquisition time reduces with the same sampling rate,
which degrades measurement accuracy. Alternatively, the sampling rate can be reduced to recover the required
acquisition time and 0.1% accuracy.

High-Gain Band Pass Filter High-Speed Peak Detector

Figure 9-3. High-Gain Narrow Bandpass Filter and Peak Detector Circuit

Ultrasonic signaling is used for proximity and obstacle detection, level sensing, sonars, and so forth. Such signal
chains detect the amplitude of received ultrasonic signal at a particular center frequency. Figure 9-3 shows a
high-gain narrow bandpass filter and peak detector circuit using any of the OPAx863 devices. The signal at the
frequency of interest is filtered out, gained, and peak detected to report the amplitude at the output of this circuit.
The phase information is lost in this circuit. The OPAx863 devices are used with the 50-MHz GBW to add a
single-stage gain and filtering, and the peak detection capability is easily made with the RRIO capability of these
amplifiers.
9.2.3 Low-Power SAR ADC Driver and Reference Buffer
Figure 9-4 shows the use of the OPAx863 as a SAR ADC input driver and reference buffer driving the ADS7945.
sensors, which are used for interface with the physical environment, exhibit high output impedance, and cannot
drive SAR ADC inputs directly. A wide-GBW amplifier, such as the OPAx863, is needed to charge the switching
capacitors at the SAR ADC input, and quickly settle to the required accuracy within the given acquisition time.
The ADC core draws transient current from the reference input during the conversion (digitization) phase, which
must be driven with a wide-GBW amplifier to offer fast settling and maintain a stable reference voltage for
excellent digitization performance. The OPAx863 reference buffer is used in a composite loop with the OPA378
precision amplifier because of limitations in precision performance of wide-GBW amplifiers. The precision
amplifier maintains low-offset output, whereas the OPAx863 devices provide the output drive and fast-settling
performance.

9.2.5 Clamp-On Ultrasonic Flow Meter


Figure 9-6 shows how ultrasonic flow meters measure the rate of flow of a liquid using transit-time difference
(t12–t21), which depends on the flow rate. Figure 9-6 shows a representative schematic for a non-intrusive
ultrasonic flow meter using the OPAx863 and 12-V transducer excitation. The OPAx863 are used for the forward
path as a unity-gain buffer for 12-V pulsed transducer excitation at NODE 1. At the same time, the receiver
circuit at NODE 2 (which also uses the OPAx863) first provides an ac-gain followed by a dc-level shift to lead to
the PGA, ADC, and processor within the MSP430™ microcontroller.
NODE 2 and NODE 1 use similar transmit and receive circuits (discussed previously) for the reverse path.
The OPAx863 wide GBW of 50 MHz introduces minimal phase-delay and low-noise for excellent flow rate
measurement. The amplifier stays in power-down mode for a majority of the time in battery-powered systems.
This configuration results in very small average system-level power consumption and prolonged battery lifetime
with the 1.5‑µA (maximum) power-down mode quiescent current with a 3-V supply. The transmit and receive
signal chains are connected to the same point at the respective node transducers. Therefore, the OPAx863
12.6-V supply voltage capability enables 12-V transducer excitation without any damage to the front-end, or a
need for external switches, thus enabling a more compact solution. These specifications make the OPAx863 an
excellent choice for flow measurements in large diameter pipes and non-intrusive flow meters. The TIDM-02003
reference design discusses an ultrasonic gas flow sensing subsystem which uses high-speed amplifiers for
front-end amplification.

9.3 Power Supply Recommendations


The OPAx863 is intended to operate on supplies ranging from 2.7 V to 12.6 V. The OPAx863 devices operate
on single-sided supplies, split and balanced bipolar supplies, or unbalanced bipolar supplies. Operating from a
single supply has numerous advantages. The dc errors, due to the –PSRR term, can be minimized with the
negative supply at ground. Typically, ac performance improves slightly at 10-V operation with minimal increase
in supply current. Minimize the distance (< 0.1 in) from the power supply pins to high-frequency, 0.01-µF
decoupling capacitors. A larger capacitor (2.2 µF typical) is used along with a high-frequency, 0.01-µF supply-
decoupling capacitor at the device supply pins. Only the positive supply has these capacitors for single-supply
operation. Use these capacitors from each supply to ground when a split-supply is used. If necessary, place the
larger capacitors further from the device and share these capacitors among several devices in the same area
of the printed circuit board (PCB). An optional supply decoupling capacitor across the two power supplies (for
split-supply operation) reduces second harmonic distortion.
9.4 Layout
9.4.1 Layout Guidelines
Achieving optimum performance with a high-frequency amplifier (like the OPAx863) requires careful attention to
board layout parasitics and external component types. The OPA2863 DGK Evaluation Module user's guide can
be used as a reference when designing the circuit board. Recommendations that optimize performance includes
the following:
1. Minimize parasitic capacitance to any ac ground for all of the signal I/O pins. Parasitic capacitance on
the output and inverting input pins can cause instability on the noninverting input and can react with the
source impedance to cause unintentional band-limiting. Open a window around the signal I/O pins in all of
the ground and power planes around those pins to reduce unwanted capacitance. Otherwise, ground and
power planes must be unbroken elsewhere on the board.
2. Minimize the distance (< 0.1 in) from the power-supply pins to high-frequency 0.01-µF decoupling
capacitors. Avoid narrow power and ground traces to minimize inductance between the pins and the
decoupling capacitors. The power-supply connections must always be decoupled with these capacitors.
Larger (2.2-µF to 6.8-µF) decoupling capacitors, effective at lower frequency, must also be used on the
supply pins. These capacitors can be placed somewhat farther from the device and shared among several
devices in the same area of the PCB.
3. Careful selection and placement of external components preserves the high-frequency performance
of the OPAx863. Resistors must be a low reactance type. Surface-mount resistors work best and allow a
tighter overall layout. Other network components, such as noninverting input termination resistors, must also
be placed close to the package. Keep resistor values as low as possible and consistent with load-driving
considerations. Lowering the resistor values keeps the resistor noise terms low and minimizes the effect
of the parasitic capacitance. Lower resistor values, however, increase the dynamic power consumption
because RF and RG become part of the amplifier output load network.

9.4.1.1 Thermal Considerations


The OPAx863 does not require heat sinking or airflow in most applications. The maximum allowed junction
temperature sets the maximum allowed internal power dissipation. Do not allow the maximum junction
temperature to exceed 150°C.
Operating junction temperature (TJ) is given by,

TJ = TA + PD x RƟJA (4)

where
• TA is the ambient temperature
• PD is the total power dissipation internal to the amplifier
• RƟJA is the junction-to-ambient thermal resistance
The total power dissipation PD = PDQ + PDL
where
• PDQ = (VS+ ‐ VS-) x IQ, is the power dissipation due to the amplifier quiescent current
• PDL(max) = VS 2 / (4 × RL), is the internal power dissipation due to the output load current
As a worst-case example, compute the maximum TJ using an OPA2863-DGK (VSSOP package) configured as
a unity gain buffer, operating on ±6-V supplies at an ambient temperature of 25°C and driving a grounded 500-Ω
load.

PD = 12 V × 2 mA + 62 / (4 × 500 Ω) = 42 mW (5)

Maximum TJ = 25°C + (0.042 W × 180.3°C/W) = 33°C, which is much less than the maximum allowed junction
temperature of 150°C.

do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.

(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.

(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
