Renesas Electronics Corporation Data Acquisition - Digital Potentiometers ISL22426WFR16Z

The ISL22426WFR16Z is a dual digitally controlled potentiometer featuring a low noise and low power design, integrated on a monolithic CMOS IC. It operates with a SPI serial interface and offers 128 taps for precise adjustments. Each potentiometer includes a volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR), allowing for easy control and recall of wiper positions upon power-up. The device can function as either a three-terminal potentiometer or a two-terminal variable resistor, making it suitable for various applications such as control and signal processing. The ISL22426WFR16Z operates within a power supply range of 2.7V to 5.5V and has a typical wiper resistance of 70Oc at 3.3V. It features a shutdown mode with a maximum shutdown current of 5¬µA. The device is available in a 16-lead QFN package and is compliant with RoHS standards. It supports a temperature range of -40¬8C to +125¬8C and has a high endurance rating of 1,000,000 data changes per bit per register, with data retention of up to 50 years at temperatures below +55¬8C.
