I broke of an audio amp(U6620 IC) on my Logic Board what does it do?

As the title, I opened up my computer to clean it from dust and I saw this small glue "ball" on the logic board and thought it was some spilled glue or something so I decided to see what it was and I tried picking it up but broke it off instead, the "glue" was actually the U6620 IC.

Arrow showing what part I mean:

Audio still works, but I'm wondering if this is bad for the audio, is the quality of the audio worse without the IC? Also, does this affect the 3.5mm headphone jack or are the speakers and the 3.5mm audio jack separate?

I don't have any warranty left but would this be possible repairing?

Thanks in advance 🙂

MacBook Pro (15-inch Early 2011), OS X Mountain Lion (10.8.2)

Here is a link to the IC: http://www.newark.com/analog-devices/ssm2375cbz-reel7/ic-audio-amp-d-3w-wlcsp-9/ dp/19T7839?CMP=AFC-SF-X-T11

And here is a link to the data sheet: http://www.farnell.com/datasheets/1793798.pdf

I've read the sheet but don't seem to understand any of it..

Most things can be repaired, although Apple won't do it except by replacing the logicboard.

If the sound works on both headphones & speakers; I'd leave it alone.

Yep, that's what I thought. How much do you think it'll cost to replace the logicboard?

Do you have any idea what the IC does? From what I understand it's a amp for the right channel or something.

If Samistar's links are correct, it must be for audio, & yet you say that it still works.

If Apple agreed to repair it, expect $300+; or perhaps under $100 if you find a third party repairer who is capable of replacing the broken IC.

Yep, it is for audio. I'm going to see if someone can repair it for me then, thanks for your help.

Does this affect the 3.5mm headphone jack aswell or is the IC only for speakers? Do you know?

Oh yes, my mistake.

I'd have expected a 3W amp to be for the speakers, rather than headphones... but there are no specs I can find quickly. You say the sound seems completely normal ?.
