Texas InstrumentsNE5532P Dual Low Noise OP Amplifier, 38 mA, Through Hole Mounting (Pack of 10)

Seem to be legit enough for my breadboard audio stuff. Lots of gain without too much noise or losing bandwidth. Will buy again if I run out.

They are exactly as described and work as they should.

ok

So much better than the originals that came in the fosi amp and I suspect those may be fake. These look different and have actual copper legs. The sound is stronger, sharper and tighter. Used these to replace op amps in other components with much improved sound quality.

I've only used one to build a voltage divider but it worked perfectly. Completely satisfied.

When an amplifier using three of these chips suddenly lost half its volume, it was easy and inexpensive to order these to test. Given that these must be in demand due to inclusion in so many popular Class D amplifiers these days, I thought they'd be harder to find. They arrived quickly and well-packaged. The ones I tried all worked, so all good!

Not sure if they are legit but they work ok.

This NE5532 op amp can put out over 30 milliamps of current.I am using it in an op amp circuit where I need more that 10 milliamps of current output.I recommend this op amp when the usual 10-20 milliamp op amps are not enough for your application.
