ISL95310 Digitally Controlled Potentiometer (XDCP™) Terminal Voltage 0V to 13.2V, 128 Taps Up/Down Interface
The ISL95310 is a digitally controlled potentiometer (XDCP) that integrates a 127‑element resistor array, wiper switches, control logic, and non‑volatile memory. The wiper position is set via an Up/Down interface and can be stored in non‑volatile memory for recall on power‑up.
Key features include a 0‑to‑+13.2 V terminal voltage range, 128 tap points with 0.8 % resolution, low standby current, and a 10‑lead MSOP package. The datasheet details absolute maximum ratings, recommended operating conditions, pin functions, and programming instructions for reliable integration into industrial and automotive control applications.
