DATASHEET
X9251
Single Supply/Low Power/256-Tap/SPI Bus, Quad Digitally-Controlled (XDCP™)
Potentiometer
The X9251 integrates four digitally controlled potentiometers
(XDCP) 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
SPI bus interface. Each potentiometer has associated with it a
volatile Wiper Counter Register (WCR) and four nonvolatile
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.
