LM4562, LME49720 and LME49860 are basically the same opamp.
LME49720 is LM4562 with a better manufacturing.
LME49860 is LME49720 with higher power supply range.
Although in my tests LME49860 it's way much noisier than LME49720 & LM4562...have no idea why. Had it tested in Voltage Amplification stage, but also in LPF (test done with LME49720 for left channel and LME49860 for right channel and noise coming from the left channel was half of the noise coming from the right).
It's like same TV brand and model, but if "Made in Japan" then it's better than "Made elsewhere".
