Renesas Electronics ISL22323
The ISL22323 integrates two digitally controlled potentiometers (DCP), control logic 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 wipers are controlled by the user through the I2C bus interface.ISL22323 NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or Dual Digitally Controlled Potentiometer (XDCP) Low Noise, Low Power, I2C Bus, 256 Taps DATASHEET FN6422 Rev.2.00 Aug 17, 2015 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 no
