DESCRIPTION
The X9Cxxx are Intersil digitally controlled (XDCP)
potentiometers. The device consists of a resistor
array, wiper switches, a control section, and nonvola-
tile memory. The wiper position is controlled by a
three-wire interface.
The potentiometer is implemented by a resistor array
composed of 99 resistive elements and a wiper switch-
ing 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 potentiom-
eter or as a two-terminal variable resistor in a wide
variety of applications including:
– control
– parameter adjustments
– signal processing
