The AD5660CRJ2 is a low power, single, 16-bit buffered voltage output digital-to-analog converter (DAC) with an integrated reference. It operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic. It incorporates an on-chip output amplifier that can drive a load of 2 kΩ. The AD5660CRJ2 uses a versatile 3-wire serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.
