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 pro-

grammed 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.
