There's probably more out there.
 
Knock yourself out.  =D

Thanks Mad Max!!

Which opamps have a colourful sound full of life, haze, and jest?
 
 
As opposed to the famous accuracy ones, (I love NE5532 from what I can tell though).
 

 

[Willakan]

Not many. Opamps are, prettymuch without exception, designed to objective criteria with lots of very expensive instrumentation.

ad797 is a single opamp - the stx uses duals - you would need 6 797s and adaptors to go from 2 singles to one dual x 3!!!!  be careful or you can damage your card if you socket 797s into the card as-is!!!!

I'm thinking of getting a OPA2107AP (DIP-8) for the buffer on my Essence STX, currently using 3 X LME49860NAs.
The ones sold in the USA sell for $16
The ones sold and shipped from China go for $4-$5.
Makes me think the ones from China are fake?

 

[Mad Max]

That or they are used but advertised as new.  They can also be new old stock.

Used, like they were cut off some old PCB board?
 
 
 

 

[Mad Max]

Desoldered from some older electronics, I guess.

 

[PurpleAngel]

Any known differences between the AD797AN & AD797BN?
And what places in the USA has the best prices on them?
Not sure I would trust any shipped from China.

 

[Mad Max]

Digikey.

 

[Tribbs]

Difference between AD797AN & AD797BN?  About $2

Brain freeze help.
 
I'd assumed AD797"N" are dual channel?
 
I see SOIC AD797 mounted on SOIC to DIP-8 adapters.
They put one AD797"R" on top and one on the bottom of the adapter.
Are the "R" mono or dual channel ICs
or do the AD797"R" come in both dual channel and mono channel?

 

[Mad Max]

There are only mono 797's.  To replace a dual opamp, you need two of them.

no warnings to the newbe that AD797 is not strictly speaking "unity gain stable"??
 
not exactly helpful - the chip needs extra external components to be stable at low gains - can't be "dropped in" to most op amp circuits, even with adapter
 
some here might benefit form this thread:

I may not share the belief system that op amp rolling is a great idea but I don't see an excuse to set people up to fail by not giving them necessary engineering information

Meh, lot's of people do it anyway.
