Datasheet or application schematics for AN7591

Nenola · 10th April 2008, 03:38 PM

Hello!

Today I salvaged some parts from a Philips stereo system which was about to go to recycle. When I opened the case, I found a working trafo and two AN7591 chips plus other stuff. I took the trafo and chips to inspect them closer. The other chip was clearly burned but the other seemed to be ok.

I'm thinking of building some kind of amp with just one chip (small sub?), but I can't find datasheet for the AN7591. Maybe someone of you DIYers could help me to find one?

I managed to view the cct for AN7591, however, the description is in a foreign language. Could a DIY'er help me translate it to English?

Thanks...

These IC's are crap! don't even bother.

Instead look at the LM3875/3886 or the TDA7293.
