Working Principles

The X9C104PIZ digital potentiometer utilizes a series of resistive elements and switches to achieve programmable resistance adjustments. The wiper terminal, controlled by the up/down and increment control inputs, moves along the resistive elements, effectively changing the resistance value seen between the high terminal and the wiper terminal. The non-volatile memory ensures that the resistance settings are retained even when power is disconnected.
