Overview
The AD5622AKSZ-2500RL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a single 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 known for its low power consumption, typically less than 100 µA at 5 V, making it ideal for battery-powered applications. The AD5622 comes in a compact 6-lead SC70 package and features an on-chip precision output amplifier that allows for rail-to-rail output swing.
