Overview
The AD5248BRMZ10-RL7, produced by Analog Devices Inc., is a dual, 256-position digital potentiometer designed for high accuracy and stability in variable resistance adjustments. This component is part of the AD5243 and AD5248 series, which offer a compact solution in a 10-lead MSOP (3 mm × 4.9 mm) package. The AD5248 performs the same adjustment function as a 2-terminal variable resistor, making it ideal for applications requiring precise resistance control.
