(1)
All limits are specified by testing or statistical analysis.
(2)
Typical values represent the most likely parametric norm.
(3)
Offset voltage average drift is determined by dividing the change in VOS at temperature extremes into the total temperature change.
(4)
Specified by design.
(5)
Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature
of 150°C.
(6)
Slew rate is the slower of the rising or falling slew rates.
