I have a low cost mic pre-amp (not a critical component in my studio) that looks fun to mod a little bit. I can't afford to put much time into this and shouldn't invest a lot either. The NE5532P is really easy to get to and I've read on the forums here and elsewhere that the Signetics NE5532AN is a better choice that the existing TI part.
Is it worth the effort to swap the two? Also, I haven't had much luck finding the data sheet for the Signetics part; is it a drop-in replacement (even with the data sheet I'd need a little hand-holding/advice as I'm not confident in this area)? I'd also be interested in in any other suggestions for drop-in replacements for the TI part.
Thanks!

Just to verify, that can serve as a direct drop-in replacement? No additional parts needed?
Thanks!
Thanks!
100 nF (small size) from V+ to V- straight on the chips pins won't hurt (aside from the standard decoupling caps from V+/V- to GND that should be there).
Thanks for putting up with the noob questions. If I'm reading the data sheet correctly, I'm connecting the capacitor from pin 4 to pin 8. Ceramic disc will be ok, right?
There should already be capacitors from V+ to ground and V- to ground but if not I can add additional 100 nf caps for this purpose...
If someone has a moment to explain, what's the function of the cap from V+ to V-? Does it stabilize the current a bit?
Again, thanks for the noob info. I'll pass it along to another noob once I've mastered it. 🙂

Where sound matters avoid ceramics. Get film-foil poly caps, e.g. Wima FKP2/FKP3.
However, I'd try BB/TI OPA2604.

I use 0.1uF 'MLCC' type caps for HF decoupling from V+ to GND and V- to GND as per an expert's suggestion.
