Note 3: These specifications are limited to -40 C≤TA≤85 C. Limits over temperature are guaranteed by design, but
not tested in production.
Note 4: The input common mode voltage of either input signal voltage should not be allowed to go negatively by
more than 0.3V (at 25oC). The upper end of the common mode voltage range is V -1.5V (at 25oC), but either or
CC
both inputs can go to +36V without damages, independent of the magnitude of the V
