Application Information
10.0 INSTRUMENTATION CIRCUITS
The LMC6482 has the high input impedance, large common-
mode range and high CMRR needed for designing instru-
mentation circuits. Instrumentation circuits designed with the
LMC6482 can reject a larger range of common-mode signals
than most in-amps. This makes instrumentation circuits de-
signed with the LMC6482 an excellent choice of noisy or
industrial environments. Other applications that benefit from

FIGURE 14. Operating from the same
Supply Voltage, the LMC6482 buffers the
ADC12038 maintaining excellent accuracy
these features include analytic medical instruments, mag-
netic field detectors, gas detectors, and silicon-based
tranducers.
A small valued potentiometer is used in series with R
the differential gain of the 3 op-amp instrumentation circuit in
Figure 15. This combination is used instead of one large
valued potentiometer to increase gain trim accuracy and
reduce error due to vibration.
