    Rev 5.00
    September 14, 2015 Low Noise/Low Power/SPI Bus Quad, 64 Tap, Digitally Controlled Potentiometer
    (XDCP™) Description Features The X9401 integrates 4 digitally controlled potentiometers
    (XDCP) on a monolithic CMOS integrated microcircuit. Quad -4 Separate Pots, 64 Taps/Pot The digitally controlled potentiometer is implemented using
    64 resistive elements in a series array. Between each
    element are tap points connected to the wiper terminal
    through switches. The position of the wiper on the array is
    controlled by the user through the SPI bus interface. Each
    potentiometer has associated with it a volatile Wiper Counter
    Register (WCR) and 4 nonvolatile Data Registers
    (DR0:DR3) that can be directly written to and read by the
    user. The contents of the WCR controls the position of the
    wiper on the resistor array through the switches. Power-up
    recalls the contents of DR0 to the WCR.
    The XDCP can be used as a three-terminal potentiometer or
    as a two-terminal variable resistor in a wide variety of
    applications including control, parameter adjustments, and
    signal processing.
