description
The TLV5625 is a dual 8-bit voltage output DAC
with a flexible 3-wire serial interface. The serial
interface is compatible with TMS320, SPI™,
QSPI™, and Microwire™ serial ports. It is
programmed with a 16-bit serial string containing
4 control and 8 data bits.

The resistor string output voltage is buffered by an x2 gain rail-to-rail output buffer. The buffer features a
Class-AB output stage to improve stability and reduce settling time. The programmable settling time of the DAC
allows the designer to optimize speed versus power dissipation.
Implemented with a CMOS process, the device is designed for single supply operation from 2.7 V to 5.5 V. It
is available in an 8-pin SOIC package in standard commercial and industrial temperature ranges.
