Each DAC includes an output buffer amplifier

The TLC7226 performance is specified for input reference voltages from 2 V to VDD − 4 V with dual supplies.
The voltage mode configuration of the DACs allows the TLC7226 to be operated from a single power supply
rail at a reference of 10 V.
The TLC7226 is fabricated in a LinBiCMOS process that has been specifically developed to allow high-speed
digital logic circuits and precision analog circuits to be integrated on the same chip. The TLC7226 has a common
8-bit data bus with individual DAC latches. This provides a versatile control architecture for simple interface to
microprocessors. All latch-enable signals are level triggered.
Combining four DACs, four operational amplifiers, and interface logic into either a 0.3-inch wide, 20-terminal
dual-in-line IC (DIP) or a small 20-terminal small-outline IC (SOIC) allows a dramatic reduction in board space
requirements and offers increased reliability in systems using multiple converters. The Leadless Ceramic Chip
Carrier (LCCC) package provides for operation at military temperature range. The pinout is aimed at optimizing
board layout with all of the analog inputs and outputs at one end of the package and all of the digital inputs at
the other.

PRINCIPLES OF OPERATION

AGND bias for direct bipolar output operation


The TLC7226 can be used in bipolar operation without adding more external operational amplifiers as shown
in Figure 4 by biasing AGND to VSS. This configuration provides an excellent method for providing a direct
bipolar output with no additional components. The transfer values are shown in Table 1.

AGND bias for positive output offset


The TLC7226 AGND terminal can be biased above or below the system ground terminal, DGND, to provide an
offset analog output voltage level. Figure 5 shows a circuit configuration to achieve this for channel A of the
TLC7226. The output voltage, VO, at OUTA can be expressed as:

V
O
+V
BIAS
)D
A
ǒVIǓ (1)

where DA is a fractional representation of the digital input word (0 ≤ D ≤ 255/256).

Increasing AGND above system GND reduces the output range. VDD − Vref must be at least 4 V to ensure
specified operation. Since the AGND terminal is common to all four DACs, this method biases up the output
voltages of all the DACs in the TLC7226. Supply voltages VDD and VSS for the TLC7226 should be referenced
to DGND.

interface logic information


Address lines A0 and A1 select which DAC accepts data from the input port. Table 2 shows the operations of
the four DACs. Figure 6 shows the input control logic. When the WR signal is low, the input latches of the
selected DAC are transparent and the output responds to activity on the data bus. The data is latched into the
addressed DAC latch on the rising edge of WR. While WR is high, the analog outputs remain at the value
corresponding to the data held in their respective latches.

unipolar output operation


The unipolar output operation is the basic mode of operation for each channel of the TLC7226, with the output
voltages having the same positive polarity as Vref. The TLC7226 can be operated with a single power supply
(VSS = AGND) or with positive/negative power supplies. The voltage at Vref must never be negative with respect
to AGND to prevent parasitic transistor turnon. Connections for the unipolar output operation are shown in
Figure 7. Transfer values are shown in Table 3.

PRINCIPLES OF OPERATION

linearity, offset, and gain error using single-ended power supplies


When an amplifier is operated from a single power supply, the voltage offset can still be either positive or
negative. With a positive offset, the output voltage changes on the first code change. With a negative offset the
output voltage may not change with the first code depending on the magnitude of the offset voltage.
The output amplifier, with a negative voltage offset, attempts to drive the output to a negative voltage. However,
because the most negative supply rail is ground, the output cannot be driven to a negative voltage.
So when the output offset voltage is negative, the output voltage remains at zero volts until the input code value
produces a sufficient output voltage to overcome the inherent negative offset voltage, resulting in a transfer
function shown in Figure 8.

Output
Voltage

0V
DAC Code
Negative
Offset

Figure 8. Effect of Negative Offset (Single Power Supply)

This negative offset error, not the linearity error, produces the breakpoint. The transfer function would have
followed the dotted line if the output buffer could be driven to a negative voltage.
For a DAC, linearity is measured between zero input code (all inputs 0) and full scale code (all inputs 1) after
offset and full scale are adjusted out or accounted for in some way. However, single power supply operation does
not allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the linearity
in the unipolar mode is measured between full scale code and the lowest code which produces a positive output
voltage.
The code is calculated from the maximum specification for the negative offset.

APPLICATION INFORMATION

bipolar output operation using external amplifier


Each of the DACs of the TLC7226 can also be individually configured to provide bipolar output operation, using
an external amplifier and two resistors per channel. Figure 9 shows a circuit used to implement offset binary

power supplies.

staircase window comparator


In many test systems, it is important to be able to determine whether some parameter lies within defined limits.
The staircase window comparator shown in Figure 10 is a circuit that can be used to measure the VOH and VOL
thresholds of a TTL device under test. Upper and lower limits on both VOH and VOL can be programmed using
the TLC7226. Each adjacent pair of comparators forms a window of programmable size (see Figure 11). When
the test voltage (Vtest) is within a window, then the output for that window is higher. With a reference of 2.56 V
applied to the REF input, the minimum window size is 10 mV.

The unity-gain output amplifier is capable of sourcing 5 mA into a 2-kΩ load and can drive a 3300-pF capacitor.
The output can be shorted to AGND indefinitely or it can be shorted to any voltage between VSS and VDD
consistent with the maximum device power dissipation.

The TLC7226 can be used as a multiplying DAC when the reference signal is maintained between 2 V and
VDD − 4 V. When this configuration is used, VDD should be 14.25 V to 15.75 V. A low output-impedance buffer
should be used so that the input signal is not loaded by the resistor ladder. Figure 14 shows the general
schematic.
