(1)

All limits are specified by testing or statistical analysis.

(2)

Typical Values indicate 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)

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