Intersil ISL22426 Dual Digitally Controlled Potentiometer Datasheet
The ISL22426 integrates two digitally controlled potentiometers and non‑volatile memory on a monolithic CMOS IC. The wiper positions are set via an SPI serial interface and can be retained after power‑down.
Key features include 128 resistor taps, a supply range of 2.7 V to 5.5 V, shutdown current of 54 µA max, and options for 10 kΩ or 50 kΩ total resistance. The device is supplied in a 14‑lead TSSOP package and is suited for control, parameter adjustment, and signal‑processing applications.
