The LT
1002 dual, matched precision operational ampli-
fiers 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 commercial grade (LT1002C) have been spec-
tacularly improved compared to presently available de-
vices.
Essentially, the input offset voltage of all units is less than
80
V, and matching between amplifiers is consistently
beter than 60
V (see distribution plot below). Input bias
and offset currents, channel separation, common mode
and power suply rejections of the LT1002C are all speci-
fied 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 adversely affecting noise or speed
performance. A by-product of lower dissipation is de-
creased 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 excellent
matching and individual amplifier specifications.
