AD5531BRUZ-REEL7

AD5531 is a single 14-bit serial input, voltage output digital-to-analogue converter (DAC). This device utilizes 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. LDAC can 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 a CLR pin allows the output to be cleared to a user-defined voltage, the potential at DUTGND. It is widely used in application such as industrial automation, automatic test equipment, process control, general-purpose instrumentation etc.
