Low Noise, Low Power, I2C® Bus, 128 TapsThe ISL22326WMVEP integrates two digitally controlledpotenTIometers (XDCP) and non-volaTIle memory on amonolithic CMOS integrated circuit.The digitally controlled potenTIometers are implemented witha combinaTIon of resistor elements and CMOS switches. Theposition of the wipers are controlled by the user through theI2C bus interface. Each potentiometer has an associatedvolatile Wiper Register (WR) and a non-volatile Initial ValueRegister (IVR) that can be directly written to and read by theuser. The contents of the WR controls the position of thewiper. At power-up, the device recalls the contents of the twoDCP’s IVR to the corresponding WRs.The DCPs can be used as three-terminal potentiometers oras two-terminal variable resistors in a wide variety ofapplications including control, parameter adjustments andsignal processing.Device InformationThe specifications for an Enhanced Product (EP) device aredefined in a Vendor Item Drawing (VID), which is controlledby the Defense Supply Center in Columbus (DSCC).“Hot-links” to the applicable VID and other supportingapplication information are provided on our website.
