ISL22329 Dual Digitally Controlled Potentiometers (XDCP™) Low Noise, Low Power, I2C™ Bus, 128 Taps, Wiper Only The ISL22329 integrates two digitally controlled potentiometers (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are 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. Each potentiometer has an associated volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR) that can be directly written to and read by the user. The contents of the WR controls the position of the wiper. At power-up the device recalls the contents of the two DCP’s IVR to the corresponding WRs. The DCPs can be used as a voltage divider in a wide variety of applications including control, parameter adjustments, AC measurement and signal processing. Features • Two potentiometers in one package • 128 resistor taps •I2C serial interface - Three address pins, up to eight devices/bus • Non-volatile storage of wiper position • Wiper resistance: 70 Ω typical @ 3.3V • Shutdown mode • Shutdown current 5µA max • Power supply: 2.7V to 5.5V •50k Ω or 10kΩ total resistance • High reliability - Endurance: 1,000,000 data changes per bit per register - Register data retention: 50 years @ T < +55°C •10 Ld MSOP • Pb-free (RoHS compliant) Pinout ISL22329 (10 LD MSOP) TOP VIEW 1 2 3 4 56 10 9 8 7 SCL RW1 GND SDA RW0 A2 A0 A1 VCC SHDN Ordering Information PART NUMBER (Note) PART MARKING RESISTANCE OPTION (k Ω) TEMP.
