X9421
Low Noise/Low Power/SPI Bus
Single Digitally Controlled (XDCP)
Potentiometer
Description
The X9421 integrates a single digitally controlled
potentiometer (XDCP) on a monolithic CMOS integrated
circuit.
The digital controlled potentiometer is implemented using 63
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. The potentiometer
has associated with it a volatile Wiper Counter Register
(WCR) and a four non-volatile Data Registers 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
though the switches. Power-up recalls the contents of the
default data register (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.
