Renesas Electronics Corporation Digital Potentiometers ISL22419UFU8Z

The ISL22419UFU8Z is a digitally controlled potentiometer featuring 128 taps and a SPI serial interface. It integrates a single potentiometer and non-volatile memory within a monolithic CMOS IC. The device operates with a power supply range of 2.7V to 5.5V and offers a total resistance option of 50kOc. The wiper resistance is typically 70Oc at 3.3V, and the device supports a shutdown mode with a maximum shutdown current of 5¬µA. This potentiometer is designed for various applications, including control, parameter adjustments, AC measurement, and signal processing. It includes a volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR), allowing for easy control and recall of the wiper position upon power-up. The device is rated for a temperature range of -40¬8C to +125¬8C and has a high endurance of 1,000,000 data changes per bit per register, with data retention of up to 50 years at temperatures below +55¬8C. The ISL22419UFU8Z is packaged in an 8-lead MSOP format and is RoHS compliant.
