Working Principles

The X9118TV14 is based on the concept of a digital potentiometer. It consists of a resistor network and control logic that allows the resistance value to be adjusted digitally. The resistance value is controlled by sending commands through the serial interface, which adjusts the wiper position within the resistor network. The non-volatile memory ensures that the resistance setting is retained even when power is removed.
