(2) Typical values represent the most likely parametric norm. (3) Slew rate is the average of the rising and falling slew rates. (4) Guaranteed based on characterization only. (5) Positive current corresponds to current flowing into the device. (6) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
