The LT1124 may be inserted directly into OP-270 sock-
ets. 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
Inmanyapplicationstheperformanceofasystemdepends
on the matching between two op amps, rather than the
individual characteristics of the two devices. The three op
ampinstrumentationamplifierconfigurationshowninthis
data sheet is an example. Matching characteristics are not
100% tested on the LT1124/LT1125.
Some specifications are guaranteed by definition. For
example, 70V maximum offset voltage implies that mis-
match cannot be more than 140V. 112dB (= 2.5V/V)
CMRR means that worst-case CMRR match is 106dB
Figure 1. Test Circuit for Offset Voltage and
Offset Voltage Drift with Temperature
(5V/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 termi-
nals, can exceed the inherent drift of the amplifier unless

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.
