I doubt they are Fakes as I have bought quite a few IC"s from that Guy....

I actually just got some LM3886s chip from that guy and the chips seem fine accept that the auction stated that the chips were LM3886T and the Ones I got were LM3886TF which I believe are the isolated ones and the LM3886T are not isolated but becides that they seem fine and the guy has a pretty good feedback rateing.....


Cheers

What you have to remember is that the OPA549 we devised by Burr-Brown before their acquisition by TI. I wouldn't be to surprised if the recent TI chips look different from BB chips due to the consolidation in packaging houses that must have occurred after the merger.
