OBSOLETE PRODUCT DATASHEET POSSIBLE SUBSTITUTE PRODUCT ISL22419 ISL22416 FN6311 Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, SPI® Rev 1.00 Bus, 128 Taps, Wiper Only September 8, 2009 The ISL22419 integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is 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. The 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.
