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 LTM4603HVEV is guaranteed to meet performance
speci?cations from 0°C to 85°C. Speci?cations over the –40°C to 85°C
operating temperature range are assured by design, characterization
and correlation with statistical process controls. The LTM4603HVIV is
guaranteed over the –40°C to 85°C temperature range.
Note 3: Remote sense ampli?er recommended for ≤3.3V output.
Note 4: 100% tested at die level only.
