3486f

Note 1: Absolute maximum ratings are those beyond which the life of a

device may be impaired.

Note 2: The LT3486E is guaranteed to meet specified performance from

0°C to 70°C and is designed, characterized and expected to meet these

extended temperature limits, but is not tested at – 40°C and 85°C.
