DESCRIPTION
The
Intersil
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.
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.
The device can be used as a three-terminal
potentiometer or as a two-terminal variable resistor in
a wide variety of applications including:
– control
– parameter adjustments
– signal processing
