DATASHEET X93254 Dual Digitally Controlled Potentiometers (XDCPs™) FN8186 Rev 1.00 February 4, 2008 The Intersil X93254 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 i
