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 +18V without damages, independent of the magnitude of the V
.
