Working Principles

The AD5220BNZ10 is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistive element with three terminals: A, W, and B. The wiper terminal (W) can be digitally adjusted to any position between the two end terminals (A and B). This adjustment is achieved by controlling the resistance value using digital signals.

The potentiometer's resistance value is controlled through an SPI interface, allowing it to be easily integrated into electronic circuits. The non-volatile memory ensures that the resistance setting is retained even when power is disconnected.
