Working Principles

The X9C102SIZ is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistor network and a wiper that can be digitally controlled. The wiper position determines the output resistance between the H and L terminals.

When the U/D input is high, the wiper moves towards the H terminal, increasing the resistance. Conversely, when the U/D input is low, the wiper moves towards the L terminal, decreasing the resistance. The INC input increments the wiper position by one step with each pulse.

The X9C102SIZ utilizes non-volatile memory to store the wiper position, ensuring it remains unchanged even after power-off. This feature allows the device to retain its settings upon power restoration.
