Q: Temperature range

 

Hi All

 

One of my customer is looking for an audio amplifier -20C to 130C ambient temperature, with 25W/channel <1%THD Four channels at 24V Dc. The Customer wants to hook 8ohms to 2 ohms speakers to it. Do we have a part, suitable for this operation.  

 

Please tell me if the TPA5630/15 part is been characterized for the temperature casing above 110degree C, I saw the Figure 10  in datasheet mentioning the same, but the Ambient temperature is mentioned as 0 – 70DegreeC. Also in TPA5630 Datasheet Figure 3 is plotted for unclipped power what is the THD associated with it.

 

Please let me know.

 

Thank you.

 

Q: Re: Temperature range

We test the part up to 125C, but operating at 130C ambient will have problems.  Most likely the device will just turn off after a short time running.  Also 24V DC is the lower end of what we support.The curves in the datasheet are taken at 1% THD for ‘unclipped’.
