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.

Note 2: The LTM4608E is guaranteed to meet performance specifications

from 0°C to 85°C. Specifications over the – 40°C to 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls. The LTM4608I is guaranteed and tested

over the –40°C to 85°C temperature range.
