Working Principles

The X9319WS8T1 digital potentiometer operates by digitally controlling the wiper position on the resistor element. The U/D input determines the direction of adjustment, while the INC input increments or decrements the wiper position. The CS input selects the device for communication. The resistance between the H and W terminals forms a voltage divider circuit, allowing the user to adjust the output voltage. The non-volatile memory ensures that the potentiometer retains its settings even when power is removed.
