Intersil ISL22319 Single Digitally Controlled Potentiometer Data Sheet
The ISL22319 integrates a single digitally controlled potentiometer (DCP) and non‑volatile memory on a monolithic CMOS IC. It offers 128 resistor taps, a low‑noise, low‑power design, and an I²C‑compatible serial interface for setting the wiper position, which can be stored in volatile and non‑volatile registers.
Key specifications include a supply voltage range of 2.7 V to 5.5 V, shutdown current of 54 µA max, wiper resistance of 70 Ω typical at 3.3 V, and endurance of 1 000 000 data changes per bit with a retention of 50 years at ≤+55 °C. The device is supplied in an 8‑lead MSOP package and is RoHS‑compliant.
