3 Description
The 12-bit DAC63204‑Q1 and 10-bit DAC53204‑Q1
(DACx3204‑Q1) are a pin-compatible family of
automotive, quad-channel, buffered, voltage-output
and current-output smart digital-to-analog converters
(DACs). The DACx3204‑Q1 devices support Hi-Z
power-down mode and Hi-Z output during poweroff
condition. The DAC outputs provide a forcesense
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 I2C, PMBus, and SPI
and contain an internal reference.
The feature set combined with the tiny package and
low power make these DACx3204‑Q1 smart DACs
an excellent choice for applications such as voltage
margining and scaling, dc set-point for biasing and
calibration, and waveform generation.
