Inverter/Sideband Suppressor project and this module looks like something
that would be a valuable addition to my system. Being a non-EE type, I have
a question about op amps for all you gurus out there.

the "NJM4558" op amp that Mouser sells? Is the Fairchild "MC4558" the same
chip too? Basically, I need to know if these chips are all interchangeable,
or if different manufacturers "build differently".
