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

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 LTM4603HVIV is

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

Note 3: Remote sense amplifier recommended for ≤3.3V output.

Note 4: 100% tested at die level only.
