ADV7391 Thermal behaviour

For the automotive version ADV7391WBCPZ the temperature range is specified for −40°C to +105°C. I assume this is ambient temperature?

Please confirm.


But the important value to make sure the part does not violate the spec is the Tjunction from the ABSOLUTE MAXIMUM RATINGS, which is speced up to 150°C, correct?


The datasheet gives 2 different thermal resistance values for junction to case (θJCtop and θJCbottom). How have both values to be combined to calculate the temperature at a given power consumption level?


best regards
