Thanks Bertus, but the one i bought is used. From the marking in the photo, there isn't any way that i can tell it is genuine or fake.
Feel worried.

Hello,

The legs are arranged like to be used in an 8 pin dil socket.
You could test the opamp on a breadboard and see if it works.
There are some test schematics in the datasheet.

You could also have a look at the PDF "opamps for everyone"

Welcome to life...
Nothing you can do about it except use/test it to see if it meets the performance/needs.. Even then you don't know if it will die tomorrow..
And life goes on..

If you were going to make a fake Burr Brown op amp,
- would you offer a op amp model that requires a metal can?
- Would you put a 1996 manufacture date in it?
- would you offer an op amp with practically no demand (one seller is offering them on eBay) and only one sold in the last month.

It seems like a lot of work for little success.

I would assume it is real.
