Overview
The AD5623RBRMZ-5REEL7, 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) designed for high precision and reliability. This device operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5623RBRMZ-5REEL7 features an on-chip reference with options for 1.25 V or 2.5 V references, allowing for full-scale outputs of 2.5 V or 5 V, respectively. The internal reference is off at power-up, enabling the use of an external reference if needed.
