Note 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 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.

Note 2: For elevated temperature operation, TJ max is +100°C

Note 3: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and

TMIN, divided by TMAX - TMIN. The measured temperatures are 0°C, 25°C and 70°C.
