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

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.
