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 Ω 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 −55˚C, 25˚C, & 125˚C or ∆VRef /(TMax −TMin) www.national.com 4 |
