The AD5530/AD5531BRU 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. 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.
The AD5530/AD5531BRU are available in 16-lead TSSOP.
