Q: TAS5630 ambient temp

Hello,

I would like to use the TAS5630 for an industrial application.

What will happe if i use it in an environment with an ambiante tempeature higher than 70°C (Reduce the MTBF, malfunction, reduce the performance?)

Is it expected in the future an  industrial range for this type of component?

Thanks


A: Re: TAS5630 ambient temp

Officially, the manufacturer (TI) does not guarantee ANY device specs or even device operation outside of the noted operating temperature range.

However, many consumer devices will operate just fine under typical 'industrial' ambient operating conditions. Specs that typically change at high temperatures include increased noise and worse power vs. thd performance.  Also, the device may go into thermal protection when outputting "normal" power levels.  For abnormal operating conditions it is best to test the specs that are important to your system at the extreme conditions.

One point that is hard to test, but is a very legitimate concern is long term device operation.  If a device is consistently operated outside of the specified conditions, long term reliability may suffer (i.e. the device may fail well before the expected lifetime is up).  Again, this goes back to the point that the manufacturer does not guarantee operation outside of the specified range.
