Ok, but still its no harm to read "TDA1541 info" anyway. The 1541 is very sensitive on a proper handling of all his pins

Bernhard that means that an TDA1541a does not need it ??

hi,

I had some detail TDA1541a info from the philips factory when I design the parallel TDA1541a D/A board.
its a PDF format approx 60~70 pages.
Anyone who had interest pls email to me.
I zip already & will email to him.
hope this can help U.

Well, these are 3 IEEE articles. If you need them, send me your Email-adress.

I guess, the Informations found their way into the comercial world:
http://www.6moons.com/audioreviews/a...abbingdon.html
"We actually analyzed the TDA1541A on an internal circuit level in extreme detail. In the process, we discovered a number of areas where correctly designed external circuitry can help to reduce the difference in linearity between the Crown and standard chips. I hope you understand that I do not wish to cover the exact details in any length. This was a research project that began in 2000 when I had published my 1999 TDA1541 non-oversampling DAC. As a result, I was provided with extensive notes (one very large and thick map of paper) on the internal design of the TDA1541 by a kind engineer at Philips Eindhoven."

And I analyzed so many crowns on a spectrum analyzer in extreme detail that all I can say is:

Hu, hu !

Most Crowns are not any better than any plain TDA1541A, so what difference should be reduced ?
