TDA 1541A Marking

Tonyb · 14th January 2005, 08:17 PM

Is anybody familiar with TDA1541A marking? My databook does not give any information on it. What do TDA1541ATC1 and TDA1541ATC2 mean?

Thanks,

TonyB

Tony,
I couldn't find anything in my books.
There are some references on Google but not helpful.
We need Jean-paul here.
Any pictures perhaps?

Hi all,

as far as I know, the "AT" is an SMD version.
As for C1 and C2, they just should be different grades.

Cheers,

Dear Tonyb,

As Carondimonio said, "AT" is an SMD version.
The production period was later than the normal DIP versions.
But if U like to build/diy 1541a kits, i still suggest the DIP version. Dip version had better punch/Bass than SMD version. This is the test result for me to compare for two version before I prepare to use in my kits.

thx

Many thanks to everybody. I do not have any pictures. These TDA1541 versions can be found for sale. However, my old Philips manual does not show any versions and this chip is already obsolete in my other manual. I was wondering if C1=S1 and C2=S2 grades but it does not seem to be the case.

Hi TonyB,

I seriously doubt about C1=S1 and C2=S2...

BTW, I' ve never found any datasheet mentioning/describing the "AT" version.

Any help in this sense would be greatly appreciated...

Cheers,

Bruno
