3 Description
The 12-bit DAC63202 and 10-bit DAC53202
(DACx3202) are a pin-compatible family of dualchannel,
buffered, voltage-output and current-output
smart digital-to-analog converters (DACs). The
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 processorless
applications and design reuse. These devices
automatically detect I2C, PMBus, and SPI 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.
