X9259

Single Supply/Low Power/256-Tap/2-Wire Bus Quad Digitally-Controlled

(XDCP™) Potentiometers

The X9259 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

2-wire 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.
