The LT1124 may be inserted directly into OP-270 sockets.
The LT1125 plugs into OP-470 sockets. Of course, all
standard dual and quad bipolar op amps can also be
replaced by these devices.

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 three
op amp instrumentation amplifier configuration shown in
this data sheet is an example. Matching characteristics are
not 100% tested on the LT1124/LT1125.
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

V/V). However, Table 1 can be used to estimate the
expected matching performance between the two sides of
the LT1124, and between amplifiers A and D, and between
amplifiers B and C of the LT1125.
Offset Voltage and Drift
Thermocouple effects, caused by temperature gradients
across dissimilar metals at the contacts to the input
terminals, can exceed the inherent drift of the amplifier
unless proper care is exercised. Air currents should be
minimized, package leads should be short, the two input
leads should be close together and maintained at the same
temperature.
The circuit shown in Figure 1 to measure offset voltage is
also used as the burn-in configuration for the LT1124/
LT1125, with the supply voltages increased to
±
16V.
