3 Description
The 12-bit DAC63202
(DACx3202) are a pin-compatible family of dual-
channel, buffered, voltage-output and current-output
smart digital-to-analog
DACx3202 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 NVM enable these smart DACs for processor-
less applications and design reuse. These devices
2
automatically detect I
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.
