(1)

Electrical Table 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.

(2)

All limits are guaranteed by testing, statistical analysis or design.

(3)

Typical values represent the most likely parametric norm 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 guaranteed on shipped production

material.

will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production

material.

(4)

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

change.
