Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT1310E is guaranteed to meet performance specifications
from 0 ° C to 70 ° C. Specifications over the – 40 ° C to 85 ° C operating
temperature range are assured by design, chacterization and correlation
with statistical process controls.
