Working Principles

The AD5241BRZ100 is based on the concept of a digital potentiometer. It consists of a resistive ladder network and a wiper that can be digitally controlled. The resistance value between the wiper and one end of the ladder determines the output voltage. By adjusting the position of the wiper digitally, the effective resistance can be changed, allowing precise resistance adjustment.
