Note 2: The LTM4602E is guaranteed to meet performance specifi cations
from 0°C to 85°C. Specifi cations over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LTM4602I is guaranteed over the
–40°C to 85°C temperature range.
Note 3: Test assumes current derating versus temperature.
