Default What about this?


I found this adaptor (PCM63 to PCM1704) in an Audio Note Dac that I bought. Is this a genuine K chip? I always thought that the grading J,K etc was added after they were marked initially, like the ones in the previous photos.

The data sheet does not say how they are marked. I was going to contact Burr Brown/Texas Instruments but their question form was longer than a contract to take out a bank loan and wanted just as much information!

Does anyone know for sure?

Thank you
