Digitally Controlled Potentiometer

(XDCP™)

The Intersil X93155 is a digitally controlled potentiometer

(XDCP). The device consists of a resistor array, wiper

switches, a control section, and nonvolatile memory. The

wiper position is controlled by a 3-wire interface.

The potentiometer is implemented by a resistor array

composed of 31 resistive elements and a wiper switching

network. 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 nonvolatile memory and then be recalled upon

during a subsequent power-up operation.

The device is connected as a two-terminal variable resistor

and can be used in a wide variety of applications including:

Pinout
