NOT FOR COMMERCIAL PURPOSES / NOT FOR RESALE / NOT FOR PROFIT.

Needed something like this for a project, so here are the open-source gerbers for free to make your own at a PCB fab of your choice.

Use this to put a 2520 size opamp in place of where a standard single DIP8 opamp would go (when applicable, of course -- can't just go around blindly swapping every single DIP8 in the world with 2520s...)

BILL OF MATERIALS:

• 6x pin receptacles/sockets: Mill Max 0322-0-15-15-34-27-10-0

• 2x 4-position single row pin header, 2.54mm spacing: Amphenol G800W304018EU or Adam Tech PH1-04-UA, or do what I do and cut your own from a long row of 2.54mm pin headers. 

You could omit one of the pin receptacles/sockets (0V) since it isn't used in the circuit.

...and as explicitly stated: this is an open-source project for D.I.Y. purposes only, not for resale and not for profit.
