rent required to trigger the SCR gate lead. The LMC6061
and LMC6081 are designed to withstand 100 mA surge cur-
rent on the I/O pins. Some resistive method should be used
to isolate any capacitance from supplying excess current to
the I/O pins. In addition, like an SCR, there is a minimum
holding current for any latchup mode. Limiting current to the
supply pins will also inhibit latchup susceptibility.

Applications
(V

)
The extremely high input impedance, and low power con-
sumption, of the LMC6081 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.

CMRR with 1 k
imbalance in bridge source resistance. In-
put current is less than 100 fA and offset drift is less than
2.5 μV/C. R
provides a simple means of adjusting gain
over a wide range without degrading CMRR. R
is an initial
trim used to maximize CMRR without using super precision
matched resistors. For good CMRR over temperature, low
drift resistors should be used.
