Analog Devices AD5512A
The AD5541A/AD5542A/AD5512A1 are single, 16-/16-/12-bit, serial input, unbuffered voltage output digital-to-analog conver- ters (DACs) that operate from a single 2.7 V to 5.5 V supply. The AD5541A/AD5542A/AD5512A utilize a versatile 3-wire interface that is compatible with a 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface standards. These DACs provide 16-/12-bit performance without any adjustments.
