(1) All limits are specified by testing or statistical analysis.
(2) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(3) Slew rate is the average of the positive and negative slew rate.
(4) Average Temperature Coefficient is determined by dividing the change in a parameter at temperature extremes by the total temperature
change.
(5) Positive current corresponds to current flowing into the device.
