Working Principles

The X9111TV14IZ is based on the principle of a digital potentiometer. It consists of a resistor network and a wiper terminal that can be moved digitally to adjust the effective resistance. The resistance value is stored in non-volatile memory, allowing it to be retained even when power is removed. The IC communicates with external devices using the I2C serial interface, enabling precise control over the resistance value.
