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.
