1. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can
be detected as this type of capacitance increases at higher frequencies.
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum
output current is approximately 40 mA independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous short-circuits
can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifi-
ers.
3. VO@1.4V, RS=0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ -1.5V).
4. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The upper end of
the common-mode voltage range is V+ -1.5V (at 25°C), but either or both inputs can go to +32V without damage independent of the magnitude of
V+.
