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 LTM4603E/LTM4603-1 are 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 LTM4603E/LTM4603-1
are guaranteed and tested over the –40°C to 85°C temperature range.
Note 3: Remote sense ampliﬁer recommended for ≤3.3V output.
Note 4: 100% tested at wafer level only.
