Working Principles

The X9317WS8T1 digital potentiometer operates by using a series of resistive elements and switches controlled digitally. The wiper terminal, connected to the internal switches, moves along the resistor array based on the digital control signals received. This movement changes the effective resistance between the wiper and the high or low terminal, allowing precise adjustment of the output voltage or current.
