Bose IC & pinouts $REWARD$

packer · 1st July 2007, 12:38 PM

Hi all,
I am looking for this IC & its pin-outs

Markings ARE:

134499 W990A9931

I would be happy to make a Donation to the person who could help
or give it back to the board

Post a pic up. What is the function of the chip? It's probably a custom Bose marked one but inside it's just a cheap chip...

This is the best I could come across back when I was looking for info on the same IC....

U2 = 134499 (Class-D driver IC)

hmmmmm

we still don't know whether the supplier have the actual stuff , don't we ?

packer · 1st July 2007, 10:59 PM

True, But at this point I have a ton of great data to go on and check.
BTW the amp i am working on is the "UX9" option out of my 2002 STS and the design is almost identical to this one.

I can not thank you enough for this!

Well, Its 11PM here, tomorrow is another day I can spend on this.
