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 ISL22323 also has 13 general purpose...
