Overview
The AD5530BRUZ, produced by Analog Devices Inc., is a single 12-bit serial input, voltage output digital-to-analog converter (DAC). This device is part of the AD5530/AD5531 family, which includes both 12-bit and 14-bit versions. The AD5530 utilizes a versatile 3-wire interface compatible with SPI®, QSPI™, MICROWIRE™, and DSP interface standards. It presents data in a 16-bit serial word format and supports daisy-chaining through the SDO pin. The DAC output is buffered by a gain of two amplifier and referenced to the potential at DUTGND, making it suitable for a variety of applications requiring precise voltage output control.
