4. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range i s V to + 32V wi thout damage.

5. Due t o the proximity of external components insure that coupling i s not originating via stray capacitance between these ext ernal parts. This typically can be detected as this t ype of capacitance increases at higher frequen ces.

6. This input current only exists when the voltage at any of t he i nput leads is driven negative. It is due to the collector-base junction of the input PN P transistor becoming forward biased and thereby acting as input diodes clamps. I n addition to this diode action, there is also NPN parasitic act ion on the IC chip. t his t ransistor act ion c a n cause t he ou t put voltag es of the Op- amps to go to the V overdrive) for the time duration than an input i s dr iven negative.
