Hi there,


I wish to try some single OP amps to replace the well known OPA2604 in an analog stage, therefore I wish to know what good single audio OP amp are pin compatible with the 2604.

Thanks in advance.

None. You'll need to use an adaptor.

As Filburt says, you'll need an adapter to use two single opamps in the socket meant for a dual opamp (which is what the OPA2604 is). You'll need to know what the supply voltage is to the opamp in your analog stage. The OPA2604 can handle up to +/-24V, which is higher than most other opamps. If your actual voltage is anywhere near that then you probably can't roll anything else in its place. Lastly, but very important, some opamps may misbehave when rolled into a circuit that they're not designed and tuned to be used in. So it's not as "plug and play" as you might think.

Thanks guys. I have 16V rated chemical caps on the board, I think the stage works under 10V.
