X9C102, Digitally Controlled Potentiometer

® Data Sheet X9C102, X9C103, X9C104, X9C503 July 20, 2009 FN8222.3 Digitally Controlled Potentiometer (XDCP™) The X9C102, X9C103, X9C104, X9C503 are Intersils’ digitally controlled (XDCP) potentiometers.

The device consists of a resistor array, wiper switches, a control section, and non-volatile 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.
