Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LT1616E 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, characterization and correlation
with statistical process controls.
