Dual, Matched Precision

Operational Amplifier

DESCRIPTION

FEATURES

The LT^®1002 dual, matched precision operational amplifiers

combine excellent individual amplifier performance with tight

matching and temperature tracking between amplifiers.

■

Guaranteed offset voltage match

In the design, processing, and testing of the device, particular

attention has been paid to the optimization of the entire

distribution of several key parameters and their matching.

Consequently,thespecificationsofeventhelowcostcommer-

cial grade (the LT1002C) have been spectacularly improved

compared to presently available devices.

LT1002A

Essentially, the input offset voltage of all units is less than

80µV, and matching between amplifiers is consistently beter

than 60µV (see distribution plot below). Input bias and offset

currents, channelseparation, commonmodeandpowersuply

rejections of the LT1002C are all specified at levels which were

previsouly attainable only on very expensive, selected grades

of other dual devices. Power dissipation is nearly halved

compared to the most popular precision duals, without ad-

versely affecting noise or speed performance. A by-product of

lower dissipation is decreased warm-up drift. For even better

performance in a single precision op amp, refer to the LT1001

data sheet. A bridge signal conditioning application is shown

below. This circuit illustrates the requirement for both excel-

lent matching and individual amplifier specifications.
