Overview
The AD5545BRU-REEL7, produced by Analog Devices Inc., is a dual, 16-bit, current-output, digital-to-analog converter (DAC). This device is designed to operate from a single supply voltage ranging from 4.5 V to 5.5 V. It features a serial data interface with a 3-wire microcontroller-compatible input using serial data in (SDI), clock (CLK), and chip select (CS) pins. The AD5545 is suitable for applications requiring high precision and low power consumption.
