DAC53204RTER

The 12-bit DAC63204, 10-bit DAC53204, and 8-bit DAC43204 (DACx3204) are a pin-compatible series of four-channel, buffered, voltage-output and current-output intelligent digital-to-analog converters (DACs). These DACx3204 devices support a high-impedance power-down mode and provide high-impedance outputs when powered down. The DAC outputs offer a force-sense option and can be used as programmable comparators and current sources. Multifunctional GPIOs, function generation, and NVM make these intelligent DACs suitable for processorless applications and design reuse. These devices automatically detect I2C, PMBus, and SPI interfaces and include an internal reference. The combination of these feature sets with a tiny package and low power consumption makes these intelligent DACs ideal for applications such as voltage margining and regulation, DC setpoints for biasing and calibration, and waveform generation.
