Overview
The AD5241BRUZ1M, manufactured by Analog Devices Inc., is a digitally controlled variable resistor (VR) device. It is part of the AD5241/AD5242 series, which provides single- or dual-channel, 256-position digital potentiometers. These devices mimic the function of traditional potentiometers, trimmers, or variable resistors but offer the advantages of digital control, higher accuracy, and longer lifespan. The AD5241BRUZ1M is particularly suited for applications requiring precise resistance adjustments and low temperature coefficient performance.
