Description
Digitally Controlled Potentiometer Xdcp?
Manufacturer
Intersil Corporation
Datasheet
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.
