Intersil ISL22349 Datasheet
The ISL22349 integrates four digitally controlled potentiometers (DCP) with non‑volatile memory on a monolithic CMOS IC. Each potentiometer offers 128 resistor taps and can be used as a voltage divider for control, parameter adjustment, AC measurement, and signal processing.
Key features include a 2.7 V‑5.5 V supply range, low shutdown current (6.5 µA max), 10 kΩ or 50 kΩ total resistance options, and a 14‑lead TSSOP package. The device supports an I²C‑compatible serial interface with up to eight devices on the bus and provides both volatile and non‑volatile registers for wiper position storage.
