Quad Digitally-Controlled (XDCP^TM) Potentiometers

FEATURES

DESCRIPTION

• Quad–Four separate potentiometers

• 256 resistor taps/pot–0.4% resolution

• 2-Wire Serial Interface for write, read, and

transfer operations of the potentiometer

The X9259 integrates

potentiometer (XDCP) on

integrated circuit.

digitally controlled

monolithic CMOS

The digital 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 a four

nonvolatile 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. Powerup recalls the contents of

the default Data Register (DR0) to the WCR.
