Renesas Electronics Corporation Digital Potentiometers ISL22316UFRT10Z-TK

The ISL22316UFRT10Z-TK is a digitally controlled potentiometer featuring 128 taps and an I2C interface. It integrates a single digitally controlled potentiometer and non-volatile memory on a monolithic CMOS IC. The device allows for control of the wiper position via the I2C bus, with a volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR) for storing the wiper position. This potentiometer can function as a three-terminal potentiometer or a two-terminal variable resistor, making it suitable for various applications such as control, parameter adjustments, and signal processing. It operates within a power supply range of 2.7V to 5.5V and has a typical wiper resistance of 70Oc at 3.3V. The device supports up to four devices on a single I2C bus due to its two address pins. The ISL22316UFRT10Z-TK is available in a 10-lead TDFN package and is RoHS compliant. It offers high reliability with an endurance of 1,000,000 data changes per bit and a data retention of 50 years at temperatures up to +55¬8C. The operating temperature range extends from -40¬8C to +125¬8C, making it suitable for industrial applications.
