Overview
The AD5162BRMZ100, produced by Analog Devices Inc., is a dual, 256-position digital potentiometer designed for precision adjustment applications. This device is packaged in a compact 10-MSOP (3 mm × 4.9 mm) and operates from a single supply voltage of 2.7 V to 5.5 V, making it suitable for a wide range of applications, including portable battery-operated devices. The AD5162 performs the same electronic adjustment function as a 3-terminal mechanical potentiometer but offers the advantages of digital control and higher accuracy.
