Hi,
I've earmarked the TAS5613 in stereo BTL mode for an aviation project. The only problem is that the qualification requirements includes operation at 85degrees Celsius ambient, while the TAS5613 is only rated to 70degrees.
However, the output power condition for the 85degrees test may be suitably derated to dop the case temperature make it pass (e.g. 50W).
Is there any information available of how the amplifier will perform at elevated ambient temperatures, or what measures can be taken to ensure operation? Also, any particular design area that will require special attention besides cooling and thermal ratings of associated parts?
Regards,
Pierre
