5 ea Burr Brown OPA637AU

[rhale64]

As it says I have 5 of these. They are authentic as I bought them a couple years ago at digikey. These were just soldered on to browndogs to try in my Marchand xover. They don't work properly because of the voltage or something I presume. So I unsoldered them and put them back in the container. I would trade for Opa627au or Opa 627 8 pin dips. I would take 80$ for all 5 and that is a steal. Or I would trade even up for the 627's . Shipping is free at this price. PayPal use friends and family or pay the fees.

Those are not unity gain stable.

Yes thank you. I have no idea what that means but that is what I read. I actually forgot the exact words.

Not good for buffer.

I have some good buffers I bought at the same time. They have never been used. I believe they are Burr Brown also. I will have to look if you're interested?

It means that the circuit must have a gain of x5 or higher for stability.

Ok I wish they would have worked. I love the 627ap I am using

Price lowered to 80 for all 5.I would trade 5 of these for 4 of the OPA627Ap or au. I can't use these so I am open for trades with the Muses dual also.

Thank you,
Ron
