DATASHEET X93256 Dual Digitally Controlled Potentiometers (XDCPs™) The Intersil X93256 is a dual digitally controlled potentiometer (XDCP).

The device consists of two resistor arrays, wiper switches, a control section, and nonvolatile memory.

The wiper positions are controlled by individual Up/Down interfaces.

A potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network.

The position of each wiper element is controlled by a set of independ
