DESCRIPTION
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.
