Texas Instruments DACx3004W Smart Digital-to-Analog Converters

Texas Instruments DACx3004W Smart Digital-to-Analog Converters (DACs) are a pin-compatible family of buffered, quad-channel, voltage-output, and current-output smart DACs. These DACx3004W support Hi-Z output during power-off conditions and Hi-Z power-down mode. The DAC outputs provide a force-sense option for use as a current sink and programmable comparator. The multifunction GPIO, NVM, and function generation enable these smart DACs for design reuse and processor-less applications. These devices automatically detect I2C, SPI, and PMBus interfaces and contain an internal reference.

The Texas Instruments DACx3004W feature set, combined with the tiny package and low power, makes these smart DACs an excellent choice for applications such as DC set-point for biasing and calibration, voltage margining and scaling, and waveform generation.
