The one on the left is from the ebay guy,the other two(549 and541) are from TI
Is the one on the left fake?

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

That’s good to know. What worried me is, how different the print looks

Thanks

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.
