Consult LTC Marketing for parts specified with wider operating temperature ranges.
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.
