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.
