[bashenan4455]

I found in national web "Performance Audio"class no LME49610. http://www.national.com/cat/index.cgi?i=i//305
BUT:At the LME49610 web : LME49610 - High Performance, High Fidelity, High Current Audio Buffer
It said is in "Performance Audio"
Why ? it is not on sale now?
And What's the difference Between LME49600 and LME49610?
Thanks.

LME49610 appears to have slightly higher bandwidth, at a higher current consumption. I think the part is just out.
