M9720AG - Quad op-amp?

[dudaindc]

More than a year ago I bought on eBay a few units of a quad op-amp that is supposed to be an OEM by National Semiconductors.
At the time the seller provided the pinout and identified this as an OEM version of a "regular production" quad op-amp.

When my brain changed from a dual to a single-neuron operation, I lost that info...

Before posting here I did several searches, but ended up empty handed.
Does anybody have any info on this component?

Thanks in advance!

I just ran into this same problem and found this one and only query on google. Maybe it's too late, maybe it's not...
Thought I'd join and post an update...

The parts I have were still in the envelope from the seller, looked in a way old email database and found the listing...

Probably bought them from the same seller.

That's wonderful: in a world dominated by internet, email, tweets, IM, etc, having two people communicating at their own leisurely pace, just like when boats took months to bring mail from one continent to the other.
A bit more slowly in fact: a question, followed more than two years later by an answer, and finally an acknowledgement after only one year and a bit....

Mmmm! I feel relaxed, that's the kind of rythm I like.
