The ISL22316WMUEP is a digitally controlled potentiometer from Intersil with low noise, low power and I2C bus interface. It can be used in a wide variety of applications including control, parameter adjustments and signal processing.
The ISL22316WMUEP integrates a single digitally controlled potentiometer (DCP) and non‑volatile memory on a monolithic CMOS IC. It can be used as a three‑terminal potentiometer or a two‑terminal variable resistor, featuring a serial I²C interface, 128 resistor taps, and non‑volatile storage of the wiper position.
The device is supplied in a 10‑lead Mini Small Outline Plastic (MSOP) package, operates from 2.7 V to 5.5 V, and is qualified for military‑temperature operation from –55 °C to +125 °C. Ordering information, pin descriptions, and mechanical dimensions are provided in the datasheet.
