Note 2: The LTM8020E is guaranteed to meet performance specifi cations
from 0°C to 85°C provided the maximum internal temperature rating is not
exceeded. Specifi cations over the –40°C to 85°C operating temperature
range are assured by design, characterization and correlation with
statistical process controls.
Note 3: Guaranteed by design.
