Novice asks for help: Are LME49720 and LM4562 the same?
Some people say that their internal structure is the same, and their manuals on TI’s website are also the same, but their prices are quite different.
Are they really the same?
thank you all;）

The elephant is in both their rooms (they have the same issues with RFI and noise), strongly suggesting the same die.

Sensitivity of opamps to air coupled EM fields, especially of the LM4562/LME497X0 family | Audio Science Review (ASR) Forum
Don't get me wrong they are top performing, but you have to be aware of the sensitivity to RFI when designing the enclosure and may have to select-on-test for best noise performance.

This is intriguing.
I have used these op amps quite a lot, and admittedly in Sallen Key filters, at unity gain - I've not noticed any RF pickup (I guess I wouldn't at unity gain)
