Per typical application (front page) configuration. ELECTRICAL CHARACTERISTICS 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. |
