Working Principles

The X9314WSIZT1 is based on the principle of a digital potentiometer. It consists of a resistive ladder network and a wiper that moves along the ladder, creating a variable resistance. The position of the wiper determines the resistance value. The IC uses a serial interface to receive digital commands and adjust the wiper position accordingly. The non-volatile memory stores the wiper position, allowing it to retain the resistance value even when power is removed.
