OPA627 in class A - swap to 134 or 604?
 
Hello!
I have a couple of OPA627 running in class A with a resistor to the negative supply.
Is it possible to just swap them for OPA134 or 604 without any modification of my class A arrangement?

Cheers,
Tom

Yes, you can.

The class A biasing will be OK, but one shouldn't glibly assume
that you can indiscriminately interchange op-amps.
