Electrical Characteristics values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in

very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables

under conditions of internal self-heating where TJ TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the

device may be permanently degraded, either mechanically or electrically.

The offset voltage average drift is determined by dividing the change in VOS at the temperature extremes by the total temperature

change.
