November 4, 2014 Low Noise, Low Power, 100 Taps, Digitally Controlled Potentiometer (XDCPв„ў)
The Intersil X9317 is a digitally controlled potentiometer
(XDCPв„ў). 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 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. 100 wiper tap points
-Wiper position stored in nonvolatile memory and recalled
on power-up 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. Low power CMOS
