Overview
The AD5675RARUZ is a low-power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the nanoDAC+ series and is designed for high precision and low power consumption. It features a 2.5 V, 2 ppm/°C internal reference and a gain select pin that allows for full-scale output of either 2.5 V or 5 V. The AD5675RARUZ operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design.
