Dual Digitally Controlled Potentiometers
(XDCPs™)
The Intersil X93255 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.
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.
Each potentiometer is connected as a two-terminal variable
resistor and can be used in a wide variety of applications
including:
• Bias and gain control
• LCD Contrast Adjustment
