isl95710 is a digitally controlled potentiometer from intersil. it can be used as a three-terminal potentiometer or as a two-terminal variable resistor. it features non-volatile solid-state potentiometer, up/down interface and chip select enable.
The Intersil ISL95710 is a digitally controlled potentiometer (XDCP) that consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The device features an Up/Down interface to control the wiper position, which can be stored in nonvolatile memory and recalled upon power-up. It is designed for use as a three-terminal potentiometer or a two-terminal variable resistor in industrial, automotive, and bias adjustment applications.
The ISL95710 offers 128 wiper tap points with 127 resistive elements and supports terminal voltages of +3V or +5V. Key specifications include a typical temperature coefficient of +50ppm/°C, low power CMOS operation with a standby current of 1µA, and high reliability with 200,000 data change endurance. The device is available in a 10-lead MSOP package.
