The 12-bit DAC63004 and 10-bit DAC53004 ( DACx3004) are a pin-compatible family of ultra-low-power, quad-channel, buffered, voltage-output and current-output smart digital-to-analog converters (DACs). These DACx3004 support Hi-Z power-down mode and Hi-Z output during 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 combined with the tiny package and ultra-low power make these smart DACs an excellent choice for applications such as land mobile radios, pulseoximeters, notebook PCs, and other battery-operated applications for biasing, calibration, and waveform generation.
