Working Principles

The CAT5112VI-10-G operates based on the principle of a digital potentiometer. It consists of a series of resistive elements connected between terminal A and terminal B, with a wiper terminal W that can be digitally controlled. By adjusting the position of the wiper, the effective resistance between terminals A and B can be changed.

The IC utilizes non-volatile memory to store the wiper position, allowing it to retain the resistance setting even when power is disconnected. This feature makes it suitable for applications where the resistance needs to be maintained across power cycles.
