TAS2563: We’re looking for large power amplifier (15~20W)

Hi, Kane,

These are some of our products that support this power level.

I'm coping some members of the MPAA team in order to get more information about the power amplifier that you are looking for.

Best regards,

Hello Kane,

Can you clarify specifics on what their main considerations are in regards to signal interference? As far as a general suggestion that supports up to 20W we can recommend the TAS5805M. If they want a smaller QFN package we offer the TAS5825M which has more advanced audio processing. Both of these are stereo devices.

Best Regards,

Luis

Hi Luis,

Thanks for asking. We have the concern of interference of RF or other high-speed signals. Of course, footprint size is also what we concerned.

We're wondering if smart amp with small output power, such as TAS2563, which are designed as mono output to aim smartphone field is because of signal interference concern? Or we could just apply one stereo channel in smartphone to reduce total footprint size. However, amp with mono output is common in smartphone filed.

On the other hand, stereo output is common in your product line when it comes to amp with large output power. Therefore, we appreciate if there's any new input of product design or marketing research could share with us. It could help us to understand which product is more suitable for us. 

BTW, we found TAS5720 is mono output with 20W output and is smaller than TAS5825. If we do need to put amp beside the speaker, it seems TAS5720 may be a better choice for us due to footprint size reduction? 

Thanks,

Bruce

hi, Bruce,

   I would suggest you check what input signal (frequency range) you will add for this application. need to check class-D bandwidth to check workable or not except output power.
