X9429
Low Noise/Low Power/2-Wire Bus Single Digitally Controlled Potentiometer
(XDCP™)
The X9429 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 2-wire 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.
