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 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
