3 Description
The 12-bit DAC63001 and DAC63002, and the 10‑bit
DAC53001 and DAC53002 (collectively referred to as
the DACx300x) are a pin-compatible family of ultra-
low-power, single-channel and dual-channel, buffered
voltage-output and current-output smart digital-to-
analog converters (DACs). The DACx300x 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 automatically detect I
PMBus, and SPI interfaces and contain an internal
reference.
The feature set combined with the tiny package and
ultra-low power make these smart DACs an excellent
choice for applications such as land mobile radios,
pulse oximeters, notebook PCs, and other battery-
operated applications for biasing, calibration, and
waveform generation.
