Overview
The AD5241BRUZ10 is a single-channel, 256-position digitally controlled variable resistor (VR) device produced by Analog Devices Inc. This device performs the same electronic adjustment function as a potentiometer, trimmer, or variable resistor. It offers a completely programmable value of resistance between the A terminal and the wiper, or the B terminal and the wiper, making it versatile for various applications.
