Working Principles

The X9429YV14Z is based on the concept of a digital potentiometer. It consists of a resistor network and a digital-to-analog converter (DAC). The resistance value can be adjusted by changing the position of the wiper within the resistor network. This is achieved by digitally controlling the DAC through the serial interface. The non-volatile memory ensures that the resistance setting is retained even when power is removed.
