3 Description

The 12-bit DAC63204W and 10-bit DAC53204W

(DACx3204W) are a pin-compatible family of quadchannel,

buffered, voltage-output and current-output

smart digital-to-analog converters (DACs). These

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

Z output during power-off condition. The DAC

outputs provide a force-sense option for use as

a programmable comparator and current source or

sink. The multifunction GPIO, function generation,

and NVM enable these smart DACs for processorless

applications and design reuse. These devices

automatically detect I2C, SPI, and PMBus interfaces,

and contain an internal reference.

The feature set combined with the tiny package and

low power make these smart DACs an excellent

choice for applications such as voltage margining and

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

waveform generation.
