The AD5530 and AD5531 are single 12-, 14-bit serial input, voltage output DACs, respectively. They utilize a versatile 3-wire interface that is compatible with SPI, QSPITM, MICROWIRETM, and DSP interface standards. Data is presented to the part in the format of a 16-bit serial word. Serial data is available on the SDO pin for daisy-chaining purposes. Data readback allows the user to read the contents of the DAC register via the SDO pin.
