Who makes and where to buy USB Audio chips?

[cv007]

I have been using a PCM2706 for quite a while as a headphone amp for quite a while (connected to an Onion Omega2 which streams mp3's)-

I also have one driving my tda8923 boards-

(although I recently blew them up when messing with the power supply voltage : ) )

probably not a great circuit board layout as I just wanted something quick, but I'm very happy with the result. I probably do not have golden ears, but it sounds pretty good to me. The music sounds great, and when there is no music its dead silent. You don't need much to get it going and works on any os. I think it makes a good little project that you can easily get working, and if its not good enough you are not out much time and money, or you can hang a dac on it via i2s (which I intended to do, but have never done).

Good test stream-

PCM 270* are good enough. 44.1, 48 khz sampling rate, same or more as humble cd audio, 98db SNR, you dont need any more fancy stuff unless if for some high end recording studio or broadcasting equipment.
I got couple of cheapo china ones scattered around for every workstation, some hooked up to pro audio kit and cant really complain about them. big step up from whats built in any laptop or motherboad. Make your own nice board with nice capacitors and off you go.

SEVERAL years ago I used the UDA1321T
It did exactly what you are looking for.
Somewhere and in some places (according to my inventory) I should have 500 pieces of this component: I do not remember to have thrown them away.
Let me know if you are interested in
