Hey guys 🙂

Don't know if I'm allow to post this here but if you're interessted in digital audio processing and class D amps you can follow my blog borstyAudio.

I will update it regulary, it's actually very new but will get more and more articles.

Thanks
Bernhard

Hi Bernhard, great work! What chipset are you using for your 125W stereo amplifier?

Cheers,
Mike

Thank you. It's a TAS5624a Chip from Texas Instruments.
I will post some more information the next days.

Hi Bernhard, nice to see your blog! So i guess that the "secret" has been uncovered now?! 😉

Bernhard, how do those flat wire Coilcraft inductors work for you? I got some samples a few years ago but never gave them a try. I figured they would need to be somehow disassembled and gapped to work with Class-D.

That D amp looks like an excellent companion for my raspberry. Any plans to take it to the production stage?

Hello Anonymous1 🙂 I like these inductors because the have a high power rating and stay very linear. I didn't have any negative experiences with them. What do you mean with disassembled and gapped?

@Rob: Yes the secret is uncovered now🙂

@retrography: A raspberry would be great for it, you could directly use the I2S output of the rasperry to power this amp.

I'm actually waiting for a new set of parts to build another amp (this one on the blog is already in use). As soon as the new amp is assembled I will make some measurements to give you some more technical details.

And yes, if there is any way I would love to go into production with this amp.

Hurray! It looks sweet 🙂
