3 Description

The DAC63202W is a 12-bit, dual-channel, buffered,

voltage-output and current-output smart digital-toanalog

converter (DAC). The DAC63202W devices

support Hi-Z power-down mode and Hi-Z output

during power-off conditions. The DAC outputs provide

a force-sense option for use as a programmable

comparator and current sink. The multifunction GPIO,

function generation, and programmable nonvolatile

memory (NVM) enable these smart DACs for

processor-less applications and design reuse. This

device automatically detects I2C, SPI and PMBus

interfaces, and contain an internal reference.

The feature set combined with the tiny package

and low power make this smart DAC an excellent

choice for applications such as voltage margining and

scaling, dc set-point for biasing and calibration, and

waveform generation.
