DESCRIPTION
The LT®1002 dual, matched precision operational amplifiers
combine excellent individual amplifier performance with tight
matching and temperature tracking between amplifiers.
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, the specifications of even the low cost commer-
cial grade (the LT1002C) have been spectacularly improved
compared to presently available devices.
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, channel separation, common mode and power suply
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.
