Working Principles

The X9317WS8IT1 is based on the concept of a digital potentiometer. It consists of a resistor network and a wiper terminal that can be adjusted digitally. The resistance between the wiper terminal and the high voltage terminal (H) determines the output voltage. By changing the position of the wiper terminal using digital control, the resistance and thus the output voltage can be adjusted.
