DATASHEET ISL95311 Digitally Controlled Potentiometer (XDCP™), Terminal Voltage 0V to 13.2V, 128 Taps I2C Interface The Intersil ISL95311 is a digitally controlled potentiometer (XDCP).

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

The wiper position is controlled by an I2C interface.

The potentiometer is implemented by a resistor array composed of 127 resistive elements and a wiper switching network.

Between each element and at either end a
