Search for LME49710 on google, go to National's page for it, click "order" and order some samples for only a few dollars :)

 

I would recommend trying the new LME49990 too, just not to be too predictable lol. It's a new chip and no one seems to have tried it in this forum yet (whatever the reason, since it's been available for a couple of months now).

Yep, I know there exists a dedicated tool... but trust me, a precision flat screwdriver and a bit of practice and you're fine anyway.

The LME49710 is a great opamps for audio.  I have built many dual channels modules for associates adn they use them in everything from soundcards to DACs.

 

I wouldn't; worry about a dedicated IC puller as it is a waste of money.  As others suggested use your finger nail or a small knife or screw driver..

I use a pair of small-nose pliers with teeth. Grab the front and back.
