Note 1: Absolute Maximum Ratings are those values beyond which the life
to the device may be impaired.
Note 2: The LT1306E 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.
Note 3: Switch current limit guaranteed by design/correlation to static
tests.
