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: Human body model, 1.5 k Ω in series with 100 pF. Note 3: Functional test. 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 6 |
