Application Information
10.0 Instrumentation Circuits
The LMC6484 has the high input impedance, large
common-mode range and high CMRR needed for designing
instrumentation circuits. Instrumentation circuits designed
with
common-mode signals than most in-amps. This makes in-
strumentation circuits designed with the LMC6484 an excel-
lent choice for noisy or industrial environments. Other appli-

cations that benefit from these features include analytic
medical instruments, magnetic field detectors, gas detectors,
and silicon-based transducers.
A small valued potentiometer is used in series with Rg to set
the differential gain of the 3 op-amp instrumentation circuit in
Figure 15 . This combination is used instead of one large val-
ued potentiometer to increase gain trim accuracy and reduce
error due to vibration.
