X9314

Single Digitally Controlled Potentiometer (XDCP™)

Product Status: Mass Production

OVERVIEW

The Intersil X9314 is a solid state nonvolatile potentiometer and is ideal for digitally controlled resistance trimming.

The X9314 is a resistor array composed of 31 resistive elements. Between each element and at either end are tap points accessible to the wiper element. 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 XDCP 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, and signal processing.
