Typical Single-Supply Applications
(V
The extremely high input impedance, and low power con-
sumption, of the LMC6062 make it ideal for applications that
require battery-powered instrumentation amplifiers. Ex-
amples of these types of applications are hand-held pH
probes, analytic medical instruments, magnetic field detec-
tors, gas detectors, and silicon based pressure transducers.
Figure 7 shows an instrumentation amplifier that features
