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.
