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. Between each element and at either end are tap

points accessible to the wiper terminal. The position of the

wiper element is controlled by the CS, U/D, and INC inputs.

The position of the wiper can be stored in non-volatile

memory and then be recalled upon a subsequent power-up

operation.

The device can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications ranging from control to signal processing to

parameter adjustment.
