*See LT1115 data sheet for definition of CCIF testing
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 three
op amp instrumentation amplifier configuration shown in
this data sheet is an example. Matching characteristics are
not 100% tested on the LT1126/LT1127.
Expected Match
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. 112dB (= 2.5
μ
V/V)
CMRR means that worst case CMRR match is 106dB
(5
μ
V/V). However, the following table can be used to
estimate the expected matching performance between the
two sides of the LT1126, and between amplifiers A and D,
and between amplifiers B and C of the LT1127.
