DATASHEET X9C102, X9C103, X9C104, X9C503 Digitally Controlled Potentiometer (XDCP™) The X9C102, X9C103, X9C104, X9C503 are digitally controlled (XDCP) potentiometers.

The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory.

The wiper position is controlled by a three-wire interface.

The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network.

Between each element and at either end are tap point
