Working Principles

The AD5170BRMZ100 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 between the wiper and one end of the ladder determines the output resistance. By adjusting the position of the wiper digitally, the effective resistance can be changed.

The IC utilizes non-volatile memory to store the wiper position, ensuring that the resistance setting is retained even when power is removed. This feature allows for consistent performance and eliminates the need for recalibration.
