Working Principles

The X9317UV8IZT1 is a digitally controlled potentiometer that utilizes non-volatile memory to retain the wiper position even when power is turned off. It consists of a resistor element connected between terminals A and B, with the wiper terminal W providing variable resistance between H and U/D control inputs.

By applying appropriate digital signals to the U/D input, the wiper position can be adjusted in small increments, allowing for precise resistance settings. The non-volatile memory ensures that the wiper position is maintained even after power cycles.
