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 LTM4601AHVE 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 LTM4601AHVI is

LTM4601AHVMP is guaranteed and tested over the –55°C to 125°C
temperature range. For output current derating at high temperature, please
refer to Thermal Considerations and Output Current Derating discussion.
Note 3: Remote sense amplifi er recommended for ≤3.3V output.
Note 4: 100% tested at wafer level only.
