Working Principles

The X9313ZMIZT1 is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistive ladder network and a wiper that can be digitally controlled. The wiper position determines the resistance between the H terminal and the GND terminal.

The potentiometer's resistance value is adjusted by sending control signals through the SPI interface. The wiper position is stored in non-volatile memory, ensuring that it remains unchanged even when power is removed.
