December 21, 2009 Low Noise, Low Power, 32 Taps Digitally Controlled Potentiometer
(XDCPв„ў)
The Intersil X9315 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. Features The potentiometer is implemented by a resistor array
composed of 31 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. 32 wiper tap points
-Wiper position stored in nonvolatile memory and
