Low Noise/Low Power/2-Wire Bus

X9428

Single Digitally Controlled Potentiometer (XDCP^™)

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 Ohm resistor array

• Resolution: 64 taps each potentiometer

• SOIC and TSSOP packages

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.
