8.0 Instrumentation Circuits
The LMC6464 has the high input impedance, large
common-mode range and high CMRR needed for designing
instrumentation circuits. Instrumentation circuits designed
with
the
LMC6464
can
common-mode signals than most in-amps. This makes in-
strumentation circuits designed with the LMC6464 an excel-
lent choice for noisy or industrial environments. Other appli-
reject
a
larger
range
of
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 three op-amp instrumentation cir-
cuit in Figure 14 This combination is used instead of one
large valued potentiometer to increase gain trim accuracy
and reduce error due to vibration.
A two op-amp instrumentation amplifier designed for a gain
of 100 is shown in Figure 15 Low sensitivity trimming is
made for offset voltage, CMRR and gain. Low cost and low
power consumption are the main advantages of this two
op-amp circuit.
Higher frequency and larger common-mode range applica-
tions are best facilitated by a three op-amp instrumentation
amplifier.
