Working Principles

The X9C103PI is based on the concept of a digital potentiometer. It consists of a series of resistive elements connected in a ladder-like configuration. The wiper terminal moves along this ladder, effectively changing the resistance between the wiper and the two end terminals. By controlling the wiper position digitally, the resistance value can be adjusted.

The X9C103PI utilizes non-volatile memory to store the wiper position. This means that even if power is removed, the IC will retain the last set resistance value. This feature is particularly useful in applications where the potentiometer needs to maintain its setting across power cycles.
