ISL22326 is a digitally controlled potentiometer from Intersil. It has 128 resistor taps and can be used as three-terminal potentiometers or as two-terminal variable resistors. It is widely used in control, parameter adjustment and signal processing.
The ISL22326 integrates two digitally controlled potentiometers (XDCP) and non‑volatile memory on a single CMOS IC. Each potentiometer offers 128 resistor taps and can be used as a three‑terminal potentiometer or a two‑terminal variable resistor, controlled via an I²C‑compatible serial bus.
Key features include a low‑power supply range of 2.7 V to 5.5 V, shutdown current of 54 µA max, 70 Ω typical wiper resistance at 3.3 V, and EEPROM endurance of 1 million write cycles. The device is offered in 14‑lead TSSOP or 16‑lead QFN packages and is RoHS compliant.
