TheAD5530/ AD5531 are single 12- and 14-bit (respectively) serial input, voltage output digital-to-analog converters (DAC).They utilize a versatile 3-wire interface that is compatible with SPI®, QSPI™, MICROWIRE™, and DSP interface standards. Data is presented to the part in a 16-bit serial word format. 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.The DAC output is buffered by a gain of two amplifier and referenced to the potential at DUTGND.LDACcan be used to update the output of the DAC asynchronously. A power-down pin (PD) allows the DAC to be put into a low power state, and aCLRpin allows the output to be cleared to a user-defined voltage, the potential at DUTGND.The AD5530 / AD5531 are available in 16-lead TSSOP.APPLICATIONSIndustrial automationAutomatic test equipmentProcess controlGeneral-purpose instrumentation
