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, T

Note 3:
Parameters identified with

Note 4:
Guaranteed and 100% production tested.
Note 5:
Guaranteed but not 100% production tested. These limits are not used to calculate average outgoing quality levels.
Note 6:
The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating
T
MAX and
T
MIN
, divided by T
MAX
- T
MIN
. The measured temperatures are 0°C, 25°C, 70°C and 85°C.
