(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but for which specific performance is not ensured. For ensured specifications and the test
conditions, see Electrical Characteristics.

(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 V
OS
at the temperature extremes by the total temperature change.
