Intersil X9317TM8Z

Description
The Intersil X9317 is a digitally controlled potentiometer (XDCPTM) consisting 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.
