ISL22313 is a single digitally controlled potentiometer (XDCP™) from Intersil Americas Inc., which features low noise, low power, I2C bus, 256 taps
The ISL22313 integrates a digitally controlled potentiometer, control logic and non‑volatile memory on a CMOS IC. It offers 256 resistor taps, a typical wiper resistance of 70 Ω at 1 mA, and can operate from a dual supply of 2.25 V‑5.5 V (VCC) and –2.25 V‑‑5.5 V (V‑). The device supports both three‑terminal potentiometer and two‑terminal variable‑resistor configurations.
The part includes 14 general‑purpose non‑volatile registers, EEPROM endurance of 1 000 000 cycles, and a retention time of 50 years at ≤+55 °C. It is specified for an industrial temperature range of –40 °C to +125 °C and meets RoHS requirements with a Pb‑free package.
