The ISL95311 is a digitally controlled potentiometer (XDCP) with a terminal voltage range of 0V to 13.2V and 128 taps. It is controlled via an I2C interface and can be used as a three-terminal potentiometer or a two-terminal variable resistor in applications such as LCD contrast control.
The Intersil ISL95311 is a digitally controlled potentiometer (XDCP) that integrates a resistor array, wiper switches, a control section and non‑volatile memory. It operates from a supply voltage of 0 V to +13.2 V and provides 128 tap points with 0.8 % resolution.
The device features a low‑power CMOS design, standby current of 2 µA, endurance of 200 k data changes per bit, and EEPROM data retention of 50 years at temperatures below +75 °C. Communication is via a standard I²C (I?C) serial interface with configurable address pins.
