Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2: The AMC3100 is guaranteed to meet performance specifications from 0°C to 70°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation with statistical process controls.
Note 3: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula:
TJ = TA+ (PD x θJA).
