    Bus, 128 Taps
    The ISL22326WMVEP integrates two digitally controlled
    potentiometers (XDCP) 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 wipers are controlled by the user through the
    I2C bus interface. Each 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. At power-up, the device recalls the contents of the two
    DCP’s IVR to the corresponding WRs.
    The DCPs can be used as three-terminal potentiometers or
    as two-terminal variable resistors in a wide variety of
    applications including control, parameter adjustments and
    signal processing. Features Specifications per DLA VID V62/08604-01XE Full Mil-Temp Electrical Performance from -55В°C to +125В°C Controlled Baseline with One Wafer Fabrication Site and
