Hi all,
I'm working on a new project that uses the audio library to play some sound effects. Nothing too fancy, so I'm planning on using the DAC output so I don't need the full audio board. I tested my code with the prop shield and it works well.
However, I'd like to put a more powerful amp on my device. I like how simple the chip chosen by Paul is to integrate, I just need something with a bit more oomph. I'm currently looking at an option from ST, but I'd be interested in hearing is anyone had any suggestions in the 10 watts (mono) or so range. I'd be willing to sacrifice a bit of power if it could run at 5v. Something that didn't require a lot external components would be ideal.
As a bonus question, does anyone have any experience connecting powered speakers to the output of the DAC? I'm wondering if I can just use a little circuit made of passives or if I need an op-amp or something more in there.
Thanks!
