説明

The ISL22346 integrates four 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 three-terminal potentiometers or as a two-terminal variable resistors in a wide variety of applications including control, parameter adjustments, and signal processing.
