strange chip UTC FM93 2822

NIC1138 · 10th May 2007, 12:17 AM

I opened up an old computer "multimedia" amplifier to savage a speaker and take a look at its guts. It loos like it's based on a small 8 pin DIP chip written

UTC FM93
2822

Does anybody has a clue of what is it?? Any relation to TDA2822, perhaps?? (but this one has 16 pins!

)

FM93 in google returns a lot of radio stations!

Good guess!

Go here: http://www.datasheet4u.com/html/T/D/...M_UTC.pdf.html

and download the pdf datasheet.

Thank you! I wanted to take a look at the output power and laugh a bit!

(1W!)

The datasheet says it's for "portable cassette players and radios"... How can someone have the nerve to use this for a table-top amplifier?...

Has anybody ever seen a nice / fine / accaptable pair of computer "multimedia speakers", like those bought on computer stores? What was the actual power and chips?...
