(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.

(2)

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

(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.

(4)

Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature

change.

(5)

Positive Bias Current corresponds to current flowing into the device.

(6)

This parameter is guaranteed by design and/or characterization and is not tested in production.
