TI DAC53202RTER

The 12-bit DAC63202 and 10-bit DAC53202 (DACx3202) are a pin-compatible family of dualchannel, buffered, voltage-output and current-output smart digital-to-analog converters (DACs). The DACx3202 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 processorless applications and design reuse. These devices automatically detect I²C, PMBus, and SPI interfaces and contain an internal reference. The feature set 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.
