    X9251
    Single Supply/Low Power/256-Tap/SPI Bus
    Quad Digitally-Controlled (XDCP)
    Potentiometer
    The X9251 integrates four digitally controlled potentio-
    meters (XDCP) on a monolithic CMOS integrated circuit.
    The digitally controlled potentiometers are imple-mented
    with a combination of resistor elements and CMOS switches.
    The position of the wipers are controlled by the user through
    the SPI bus interface. Each potentiometer has associated
    with it a volatile Wiper Counter Register (WCR) and four
    non-volatile Data Registers that can be directly written to and
    read by the user. The content of the WCR controls the
    position of the wiper. At power-up, the device recalls the
    content of the default Data Registers of each DCP (DR00,
    DR10, DR20, and DR30) to the corresponding 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.
