X9317

Low Noise, Low Power, 100 Taps, Digitally Controlled Potentiometer (XDCP™)

The Intersil X9317 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 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 nonvolatile memory and

then be recalled upon a subsequent power-up operation.

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

voltage control or as a two-terminal variable resistor for current

control in a wide variety of applications.
