Preliminary Information

Programmable Analog

X9438

Dual Programmable Operational Ampliﬁer

FEATURES

DESCRIPTION

• Two CMOS Rail To RailOperational 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 Potentiometers

—Dual 64 Tap potentiometers

The X9438 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 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 complete stand-alone

ampliﬁers.

The digitally controlled potentiometers consist of a series

string of 63 polycrystalline resistors that behave as

standard integrated circuit resistors. The two-wire 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

restoration of the wiper position.

—R

= 10kΩ

total

—Two-wire serial interface

—V = 2.7V to 5.5V

A wide variety of applications can be implemented using

the potentiometers and the ampliﬁers. A typical

application is to implement the ampliﬁer as a wiper buffer

in circuits that use the potentiometer as a voltage

reference. The potentiometer can also be combined with

the ampliﬁer yielding a digitally programmable gain

ampliﬁer or programmable current source.
