Looks interesting. I wonder why the overview page states -110dBc THD+N @ 500KHz while the product page states 93, and the datasheet seems to indicate 95. Also wonder why it costs less than half what the AD797 costs when it appears to be indicated to use the same process and the same or similar topology, whilst being considerably faster.

This opamp caught my interest also. Very good specs.

It's worth noticing that this opamp has a powerpad also

I already got a couple of samples from AD and had a chance to quickly evaluate them. They are very, very good. I would always trust the data sheet over any marketing overwiev.

Don't know about the pricing, but I'm not sure if it's in the same process as AD797. About distortions, for +/-15V, loads over 1KOhm and and a few volts output swing, you can count for distortions in the audio frequency range of better than -110dB.

The website says 1.91 USD

AD8599 seems to be very nice too.

That's in large quantities. Expect $5 for singles via distributors, still very good.

I suppose this might be the best opamp for audio ever made.
