ผมได้ลองอ่านเว็บนอกเกี่ยวกับ Opamp อยู่เพลินๆแล้วไปเจอมาว่า
LME49720 = LM4562
คือเค้าบอกว่า LME49720 คือ LM4562 ที่เปลี่ยนชื่อใหม่เฉยๆ???
Digikey apparently knows that the LM4562 and the LME49720 are the same part. They don't stock both. They have the LME49710 and 40, but they have the dual listed only as the LM4562.
A distributor that calls on me at work has a theory about why it is dual numbered. As an earlier note said, National had re-numbered their audio line to LME so it needed a place in that listing. But after the LM4562 won all sorts of awards (EDN product of the year, etc.) National had to leave the old number in the catalog because lots of people already knew it by LM4562. In fact, National has a significant promotional campaign tied to the old number.

ซึ่งผมลองดู Datasheet แล้วมันก็เหมือนกันทุกอย่างเลยคับ
