Comment on op amp performance: what factors affect quality? Example case ua741 (bottom) versus NE5532 (top) audio signals, why is NE5532 better, what specific factors contribute to its superiority?

The difference you’re seeing is gain bandwidth product. en.m.wikipedia.org/wiki/Gain–bandwidth_product the 741 rolls off at 1MHz and the 5532 rolls off at 10MHz, so it’ll go about a decade higher frequency at about the same performance.

If you want the layout difference, in the 741 datasheet look at section 7.2, and on the ne5532, section 8.2, the schematic is different.

On top of that, the 741 was released in 1968, vs 1979 for the 5532. 10 years is huge.
