The ISL95711 is a digitally controlled potentiometer (XDCP) with terminal voltage of ±3V or ±5V, 128 taps, and I2C serial interface. It consists of a resistor array, wiper switches, a control section, and nonvolatile memory.
The ISL95711 is a digitally controlled potentiometer (XDCP) with 128 tap positions, implemented using a resistor array and wiper switches. It features a non-volatile memory that stores the initial wiper position for recall after power interruption. The device supports 10kΩ or 50kΩ resistance options and operates on a dual-supply voltage range from -5.5V to +5.5V. It is designed for industrial and automotive control, amplifier biasing, and parameter adjustments.
The datasheet details electrical specifications, including temperature coefficients, leakage current, and operating conditions. It also covers the I2C serial interface with timing parameters and pin configurations for the 10-lead MSOP package. The device is low-power, with standby current as low as 1µA, and offers high reliability with 200,000 data change endurance and 50-year data retention.
