DESCRIPTION
The TLV5630, TLV5631, and TLV5632 are pin-compatible, eight-channel, 12-/10-/8-bit voltage output DACs
each with a flexible serial interface. The serial interface allows glueless interface to TMS320 and SPI, QSPI, and
Microwire serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits.
Additional features are a power-down mode, an LDAC input for simultaneous update of all eight DAC outputs,
and a data output which can be used to cascade multiple devices, and an internal programmable band-gap
reference.
The resistor string output voltage is buffered by a rail-to-rail output amplifier with a programmable settling time to
allow the designer to optimize speed vs power dissipation. The buffered, high-impedance reference input can be
connected to the supply voltage.
Implemented with a CMOS process, the DACs are designed for single-supply operation from 2.7 V to 5.5 V, and
can operate on two separate analog and digital power supplies. The devices are available in 20-pin SOIC and
TSSOP packages.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

APPLICATION INFORMATION
GENERAL FUNCTION
The TLV5630/31/32 are 8-channel, single-supply DACs, based on a resistor string architecture. They consist of a
serial interface, a speed and power-down control logic, an internal reference, a resistor string, and a rail-to-rail
output buffer.
The output voltage (full scale determined by reference) for each channel is given by:
SERIAL INTERFACE
A falling edge of FS starts shifting the data on DIN starting with the MSB to the internal register on the falling
edges of SCLK. After 16 bits have been transferred, the content of the shift register is moved to one of the DAC
holding registers, depending on the address bits within the data word. A logic 0 on the LDAC pin is required to
transfer the content of the DAC holding register to the DAC latch and to update the DAC outputs. LDAC is an
asynchronous input. It can be held low if a simultaneous update of all eight channels is not needed.
For daisy-chaining, DOUT provides the data sampled on DIN with a delay of 16 clock cycles.

PRESET
The outputs of the DAC channels can be driven simultaneously to a predefined value stored in the preset register
by driving the PRE input pin low and asserting the LDAC input pin. The preset register is cleared (set to zero) by
the POR circuit after power up. Therefore, it must be written with a predefined value before asserting the PRE
pin low, unless zero is the desired preset value. The PRE input is asynchronous to the clock.

If DOUT is enabled, the data input on DIN is output on DOUT with a 16-cycle delay. That makes it possible to
daisy-chain multiple DACs on one serial bus.

In power-down mode, the amplifiers of the selected DAC pair are disabled and the total power consumption of
the device is significantly reduced. Power-down mode of a specific DAC pair can be selected by setting the PXY
bit within the data word to 1.
There are two settling time modes: fast and slow. Fast mode of a DAC pair is selected by setting SXY to 1 and
slow mode is selected by setting SXY to 0.

REFERENCE
The DAC reference can be sourced internally or externally by programming bits D2 (R1) and D1 (R0) of the
CTRL0 register (address = 08h). If an external source of reference is applied to the REF pin, the device must be
configured to accept the external reference source by setting R1 and R0 to 00 or 01. If R1 and R0 is set to select
for internal reference, a voltage of 1.024 V (if R1 and R0 = 10) or 2.048 V (if R1 and R0 = 11) is available. The
internal reference can source up to 1 mA, therefore. it can be used as an external system reference. A
decoupling capacitor must be connected to the REF pin if internal reference is selected to ensure output stability.
A 1 µF to 10 µF capacitor in parallel to a 100 pF capacitor should be sufficient, see Figure 13.

BUFFERED AMPLIFIER
The DAC outputs are buffered by an amplifier with a gain of two, which are configurable as Class A (fast mode)
or Class AB (slow or low-power mode). The output buffers have near rail-to-rail output with short-circuit
protection, and can reliably drive a 2-kΩ load with a 100-pF load capacitance.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
