Overview
The AD5623RBCPZ-3R2, 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 precision of 5 ppm/°C. The AD5623RBCPZ-3R2 is particularly suited for applications requiring high accuracy and low power consumption, making it ideal for portable, battery-operated equipment.
