Texas Instruments DACx3204/DACx3204-Q1 Digital-to-Analog Converters
Texas Instruments DACx3204/DACx3204-Q1 Digital-to-Analog Converters (DACs) are 12-bit (DAC63204/DAC63204-Q1), 10-bit (DAC53204/DAC53204-Q1), and 8-bit (DAC43204/DAC43204-Q1) quad-channel, buffered voltage-output, and current-output smart DACs. These DACx3204 support Hi-Z power-down mode and Hi-Z output during the power-off condition. 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 I2C, PMBus, and SPI interfaces and contain an internal reference.
The feature set of the Texas Instruments DACx3204/DACx3204-Q1, 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. The DACx3204-Q1 devices are AEC-Q100 qualified for automotive applications.
