Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction
to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax =(TJmax -TA)/θJA or the
number given in the Absolute Maximum Ratings, whichever is lower.
Note 3: Human body model, 1.5K
in series with 100pF.
Note 4: The average temperature coefficient is defined as the maximum deviation of reference voltage, at all measured temperatures between the operating TMin
&TMax, divided by (TMax TMin). The measured temperatures (TMeasured) are 55C, 25C, & 125C or VRef /(TMax TMin)
