Guest Kasamiko Posted March 29, 2004 Report Share Posted March 29, 2004 Hi mate..I just encountered this amplifier with weird chip marking. ???the chips looks like ordinary AN7161, with 12 pins. Obviously the original number was erased and replaced with this "TA5555"! >:(I've search the net and can't find any device with this marking...So i decided to trace the circuit and make a rough diagram out of it..Hoping for any suggestion..Thanks.

hotwaterwizard Posted March 29, 2004 Report Share Posted March 29, 2004 I assume it is out of a car stereo. The number reads like a Toshiba Chip. What brand of stereo is it out of and model # Quote Link to comment Share on other sites More sharing options...

MP Posted March 30, 2004 Report Share Posted March 30, 2004 SGS Thompson made several power amp chips like these which were a TDAxxxx, where the x is a number. You might try a cross there, and then try to cross a TDA number over to NTE as they seemed to have quite a few of their equivalent parts.I will also keep looking in some of the data I have.Here is a site with several of the TDA data sheets. You might find a similar one: http://users.otenet.gr/~athsam/database.htmMP Quote Link to comment Share on other sites More sharing options...

hotwaterwizard Posted March 31, 2004 Report Share Posted March 31, 2004 Do you know the manufacture of the Kit? Maybe the Kit # Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted April 1, 2004 Report Share Posted April 1, 2004 It appears to be a Mono IC chip. Sometimes TA and KIA are interchangable.I am not giving up on it until I get all of the info or until I get to this Link.http://www.datamath.net/ Quote Link to comment Share on other sites More sharing options...
