Overview
The AD5623RBCPZ-3REEL7, 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 AD5623RBCPZ-3REEL7 features an on-chip reference with a 1.25 V, 5 ppm/°C precision, providing a full-scale output of 2.5 V. The on-chip reference can be turned on or off, allowing for the use of an external reference if needed.
