Digital Potentiometers datasheet and documents for ISL22444WFR20Z

ISL22444WFR20Z

Digital Potentiometers Overview

The ISL22444WFR20Z is a quad digitally controlled potentiometer (XDCP) featuring 256 resistor taps and an SPI serial interface. It integrates four DCPs, control logic, and non-volatile memory on a monolithic CMOS IC. The device supports dual power supplies with VCC ranging from 2.25V to 5.5V and V- from -2.25V to -5.5V, enabling bipolar operation. It offers 10kΩ total resistance in a 20-lead QFN package. Key specifications include a typical wiper resistance of 70Ω, standby current under 4µA, and extended industrial temperature range from -40°C to +125°C.

Digital Potentiometers Feature Summary
