Overview
The AD5623RBRMZ-5, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low-power, dual 12-bit buffered voltage-out digital-to-analog converter (DAC) that operates from a single 2.7 V to 5.5 V supply. This device is guaranteed monotonic by design and features an on-chip reference with a 2.5 V, 5 ppm/°C precision, providing a full-scale output of 5 V. The AD5623RBRMZ-5 is designed for applications requiring high precision and low power consumption, making it ideal for portable, battery-operated equipment.
