It's usually in a company's best interests to keep as much as possible secret, why would you want to educate your competitors?

An exception to the rule is a patent. Have you tried searching patent databases?

I know all of this, but I need more detailed information, as is available for tda1540 or 1541.
Also application Notes, it all somehow looks secret, what about TDA1544, what is it? Why was only in one device and otherwise hardly any information ..

Hi,

If you need the datasheets, you can find them here

If you read the Lampiazator website, a word of warning : our Polish friend has a very peculiar idea on technology. Check his ideas double for consistency !

Succes, Herman

Good day!
Would like to ask if you can help me.
I am looking for all information regarding old Philips DAC Series:
TDA1544;
TDA1543;
TDA1545;
TDA1387.
I'm interested in all kinds of technical information, technology, history, technological differences compared to TDA1541.
Maybe you know the sources where you can get such information.
Thanks in advance!
