February 1, 2008 Dual Digitally Controlled Potentiometers (XDCPs™)
The Intersil X93256 is a dual digitally controlled
potentiometer (XDCP). The device consists of two resistor
arrays, wiper switches, a control section, and nonvolatile
memory. The wiper positions are controlled by individual
Up/Down interfaces. Features
• Dual solid-state potentiometers
• Individual Up/Down interfaces
• 32 wiper tap points per potentiometer
-Wiper position stored in nonvolatile memory and
recalled on power-up A potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. The position of each wiper element is controlled by
a set of independent 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. • 31 resistive elements per potentiometer
-Temperature compensated
-Maximum resistance tolerance of ±25%
-Terminal voltage, 0 to VCC Each potentiometer is connected as a three-terminal
variable resistor and can be used in a wide variety of …
