Long Term Stability
(Note 4)
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:
Parameters identified with
boldface type
apply at temperature extremes. All other numbers apply at T
A
= T
J
= 25°C.
Note 3:
Guaranteed and 100% production tested
Note 4:
Guaranteed but not 100% production tested. These limits are not used to calculate average outgoing quality levels.
Note 5:
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 -40
