Note 2: The LTM4604E 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 LTM4604I is guaranteed over the full
–40°C to 85°C temperature range.
