ISL96017 is a 128-bit digitally controlled potentiometer from Intersil, integrated with 16kbit of EEPROM and a 2-wire I2C serial interface. The device is powered by a single 3.3V supply and is available with either 10kΩ or 50kΩ total resistance.
The ISL96017 integrates a 128‑tap digitally controlled potentiometer, 16 kbit EEPROM, and a two‑wire I²C serial interface. The device operates from a single 3.3 V supply and offers total resistance options of 10 kΩ or 50 kΩ. The potentiometer terminals can be used as a variable resistor or a resistor divider, and the wiper position can be stored in non‑volatile memory for recall after power‑up.
The part is supplied in an 8‑lead thin dual‑flat no‑lead (TDFN) package (3 mm × 3 mm). Key features include 128 tap positions, 50‑year EEPROM retention at <55 °C, 1 M write cycles, and operation over –40 °C to 85 °C ambient temperature.
