Quad Digitally Controlled Pote Dnatitoam Sehteere(t XDCP™) Low Noise,ALuogwus Pto1w7e, r2, 0I21C5 Bus, 256 Taps FN6423 Rev 2.00 August 17, 2015 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 bination 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. The ISL22343 also has 11 general purpose non-volatile registers that can be used as storage of lookup table for multiple wiper position or any other...
