=-40 to 85 o C (Note 3)
Note 3: These specifications are limited to -40 o C ≤T
A
≤85 o 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 25
o C ). The upper end of the common mode voltage range is V
CC
-1.5V (at 25 o C ), but either or
both inputs can go to +36V without damages, independent of the magnitude of the V
CC
.
