Matching Specifications
In many applications the performance of a system de-
pends on the matching between two op amps, rather than
the individual characteristics of the two devices. The two
and three op amp instrumentation amplifier configura-
tions shown in this data sheet are examples. Matching
characteristics are not 100% tested on the LT1078/LT1079.
W
U
Some specifications are guaranteed by definition. For
example, 70
μ
V maximum offset voltage implies that mis-
match cannot be more than 140
μ
V. 97dB (= 14
μ
V/V)
CMRR means that worst-case CMRR match is 91dB
(= 28
μ
V/V). However, Table 1 can be used to estimate the
expected matching performance at V
S
= 5V, 0V between
the two sides of the LT1078, and between amplifiers A and
D, and between amplifiers B and C of the LT1079.

Comparator Applications
The single supply operation of the LT1078/LT1079 and its
ability to swing close to ground while sinking current
lends itself to use as a precision comparator with TTL
compatible output.
