DESCRIPTION
The Intersil X93254 is a dual digitally controlled poten-
tiometer (XDCP). The device consists of two resistor
arrays, wiper switches, a control section, and nonvola-
tile memory. The wiper positions are controlled by indi-
vidual Up/Down interfaces.
A potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switch-
ing 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 non-
volatile memory and then be recalled upon a subse-
quent 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
