X9258US - Quad Digital Controlled Potentiometers (XDCP)

DESCRIPTION

The X9258 integrates 4 digitally controlled

potentiometers (XDCP) on a monolithic CMOS

integrated circuit.

The digitally controlled potentiometer is implemented

using 255 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. Each potentiometer has

associated with it a volatile Wiper Counter Register

(WCR) and 4 nonvolatile Data Registers (DR0:DR3)

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 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.
