Working Principles

The X9268US24IZ digital potentiometer operates by digitally controlling the resistance value between its wiper terminal (W) and the two end terminals (A and B). The desired resistance value is set using the SPI interface, and the IC stores this setting in its non-volatile memory. When powered on, the IC adjusts the resistance accordingly, allowing precise control over the circuit it is connected to.
