Working Principles

The X9318WS8I is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistive element and a wiper that can be digitally adjusted. The resistance value between the wiper terminal and either end terminal can be varied by sending commands through the I2C interface. The non-volatile memory ensures that the wiper position is retained even when power is removed.
