X9428 Low Noise/Low Power/2-Wire Bus

Single Digitally Controlled Potentiometer (XDCP™)

FN8197

Rev 1.00

April 26, 2006

FEATURES

DESCRIPTION

• Solid state potentiometer

• 2-wire serial interface

• Register oriented format

—Direct Read/Write/Transfer wiper position

—Store as many as four positions per

potentiometer

The X9428 integrates

potentiometers (XDCP) on a monolithic CMOS

integrated microcircuit.

digitally controlled

The digitally 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. 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 through the switches. Power-up recalls

the contents of DR0 to the WCR.

• Power supplies

—V

= 2.7V to 5.5V

—V+ = 2.7V to 5.5V

—V– = -2.7V to -5.5V

• Low power CMOS

—Standby current < 1µA

—Ideal for battery operated applications

• High reliability

—Endurance–100,000 Data changes per bit per

—Register data retention–100 years

• 4-bytes of nonvolatile memory

• 10k resistor array

• Resolution: 64 taps each potentiometer

• 16 Ld SOIC, 14 Ld TSSOP packages

• Pb-free plus anneal available (RoHS compliant)

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.
