    ISL22343UFR20Z-TK Product overview

    Low Noise, Low Power, I2C Bus, 256 Taps The ISL22343 integrates four digitally controlled potentiometers (DCP), control logic and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the I2C bus interface. The potentiometer has an associated volatile Wiper Register (WRi) and a non-volatile Initial Value Register (IVRi) that can be directly written to and read by the user. The contents of the WRi control the position of the corresponding wiper. At power up the device recalls the contents of the DCP’s IVRi to the correspondent WRi. Features • Four potentiometers in one package • 256 resistor taps • I2C serial interface    - Three address pins, up to eight devices per bus • Non-volatile EEPROM storage of wiper position • 11 General Purpose non-volatile registers • High reliability    - Endurance: 1,000,000 data changes per bit per register    - Register data retention: 50 years @ T 55°C • Wiper resistance: 70 typical @ 1mA • Standby current <4µA max • Shutdown current <4µA max • Dual power supply    - VCC = 2.25V to 5.5V    - V- = -2.25V to -5.5V • 10k, 50k or 100k total resistance • Extended industrial temperature range: -40°C to +125°C • 20 Ld TSSOP or 20 Ld QFN • Pb-free (RoHS compliant)
