Working Principles

The X9313WST1 is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistive ladder network and a wiper that moves along the ladder based on digital control signals. The resistance between the wiper and one of the terminals determines the output voltage.

When a digital value is sent through the SPI interface, the wiper position changes accordingly, allowing precise control of the resistance. The non-volatile memory ensures that the wiper position is retained even when power is disconnected.
