Voltage Margining and Scaling Using the DAC63202W
2 Applications
• Optical module
• High performance computing
• Standard notebook PC
3 Description
The DAC63202W is a 12-bit, dual-channel, buffered,
voltage-output and current-output smart digital-to-
analog 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 I
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.
