Intersil ISL95711WIU10Z-T

Description
The Intersil ISL95711 is a digitally controlled potentiometer (XDCP) consisting 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. The wiper terminal can be connected to either end of the resistor array or at any one of the Tap Positions in between, providing 128 steps of resolution between RL and RH. The "position" of the wiper is determined by the value assigned to the volatile Wiper Register (WR). This register has an associated non-volatile Initial Value Register (IVR). The value stored in the IVR will be written into the WR at power-up, allowing wiper position recall after power interruption. The WR and the IVR can be directly written to and read from using standard I²C interface protocol.
