Preliminary Information

Programmable Analog

X9430

Dual Digitally Controlled Potentiometer (XDCP^™) with Operational Amplifier

FEATURES

DESCRIPTION

• Two CMOS voltage operational amplifiers

• Two digitally controlled potentiometers

• Can be combined or used separately

• Amplifiers

—Low voltage operation

—V+/V- = ±2.7V to ±5.5V

—Rail-to-rail CMOS performance

—1MHz gain bandwidth product

• Digitally controlled potentiometer

—Dual 64 tap potentiometers

The X9430 is a monolithic CMOS IC that incorporates

two operational amplifiers and two nonvolatile digitally

controlled potentiometers. The amplifiers are CMOS

differential input voltage operational amplifiers with

near rail-to-rail outputs. All pins for the two amplifiers

are brought out of the package to allow combining

them with the potentiometers or using them as com-

plete stand-alone amplifiers.

The digitally controlled potentiometers consist of a

series string of 63 polycrystalline resistors that behave

as standard integrated circuit resistors. The SPI serial

port, common to both pots, allows the user to program

the connection of the wiper output to any of the resistor

nodes in the series string. The wiper position is saved

in the on board E2 memory to allow for nonvolatile res-

toration of the wiper position.

= 10k¾

total

—SPI serial interface

—V = 2.7V to 5.5V

A wide variety of applications can be implemented

using the potentiometers and the amplifiers. A typical appli-

cation is to implement the amplifier as a wiper buffer in

circuits that use the potentiometer as a voltage refer-

ence. The potentiometer can also be combined with

the amplifier yielding a digitally programmable gain

amplifier or programmable current source.
