Help identifying IC with "M9" embossed in a circle

Postby Deaj » 09 Feb 2008, 08:28

I have an IC I'm using in one of my builds that I cannot identify. I'm not sure when I acquired it. The lettering on the top has been removed. The only distinguishing feature is a circle on the bottom of the chip with the characters "M9" embossed on the surface inside the circle. I tried to take pictures but my camera doesn't capture enough detail to be of any assistance. I'll see about borrowing a camera tomorrow to get some pics posted. In the meantime I figured I'd ask if anyone here knows of an IC with "M9" embossed on the bottom.

The closest sonic match I was able to make is the LF353P. The unknown IC is a touch more compressed and smoother highs. The LF353P is really close but not the same. I hope to be able to identify this IC as I'd like to use it in another build.

Any help is appreciated. :)
