Description
The ISL22424 integrates two digitally controlled potentiometers (DCP), control logic 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 wiper is controlled by the user through the SPI serial interface. Each 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 wiper. At power-up the device recalls the contents of the DCP's IVRi to the corresponding WRi. The ISL22424 also has 13 General Purpose non-volatile registers that can be used as storage of lookup table for multiple wiper position or any other valuable information. The ISL22424 features a dual supply, that is beneficial for applications requiring a bipolar range for DCP terminals between V- and VCC. Each DCP can be used as three-terminal potentiometer or as two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.
