Quad Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, SPI® Bus, 256 Taps
DATASHEET
FN6426 Rev 0.00 May 24, 2007
The ISL22444 integrates four 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 wipers position 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.
