Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
temperature range are assured by design, characterization and correlation  
with statistical process controls. The LTM4600I is guaranteed over the  
–40°C to 85°C temperature range.  
Note 3: Test assumes current derating versus temperature.  
Note 4: Guaranteed by correlation.  
Note 2: The LTM4600E is guaranteed to meet performance specifications  
from 0°C to 85°C. Specifications over the –40°C to 85°C operating
