Overview
The AD5243BRMZ100, produced by Analog Devices Inc., is a dual, 256-position digital potentiometer. This component is designed to provide a compact solution for various adjustment applications, similar to a 3-terminal mechanical potentiometer. It is packaged in a 10-lead MSOP (3 mm × 4.9 mm) package, making it ideal for space-constrained designs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and consumes a maximum of 6 µA, making it suitable for battery-operated and portable applications.
