Note 2: The LTM4601E/LTM4601E-1 are 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 LTM4601I/LTM4601I-1
are guaranteed and tested over the –40°C to 85°C temperature range.
Note 3: Remote sense amplifi er recommended for ≤3.3V output.
Note 4: 100% tested at wafer level only.
Note 5: Limit current into RUN pin to less than 1mA.
