Selecting amplifier advice

Other Parts Discussed in Thread: TLV320AIC3254, TPA2025D1, TPA2008D2

Hello all,

For years, I have been disappointed in store bought headphones, So I have decided to build my own. I want to use these speakers. The speakers are 5W, and fit great in the headphones I am using. But I am having trouble deciding what would be the best amplifier I should go with. Here is what I want the final design to be;

  • High power (I like to listen to music loud)
  • battery powered (2 or 3 cell Li-ion in series)
  • very low noise
  • DSP controlled (Working with TLV320AIC3254 DSP)
  • BlueTooth

Right now I am only worried about the amplifier. The rest will come in time. I cant have any BGA packages, OSHpark cant do BGA's. 

Does anyone have any options or ideas on an amplifier that would fit the bill?

Thanks

Anthony

    Hi Anthony,

    That's really cool!, we have plenty options on the low power amplifier selection, you may take a look to our Audio Selection Tool. Do you prefer a mono or stereo amplifier?, you can take a look to our TPA2025D1, this device features an integrated battery tracking feature that controls the gain to limit battery current at lower battery voltage. TPA2008D2 could be an option as well.

    Hello Diego,

    Thank you, I thought it is cool too.

    I like the TPA2025D1, but sadly, OSHpark doesn't have the capabilities for BGA packages. 

    The TPA2008D2 is a great option. And the wattage is closer to the 4 watts RMS the speakers have. I dont think I need more than that. It all depends on how the low end response is.

    Thank you so much for the advice. I now have a direction I can follow. 

    Anthony
