Audio amplifier

[Mukhalled]

Hi

I would like to build my own audio amplifier for my car but I don´t know which of these projects fits. I want it to be for ex. 2x45W 12V DC.
Can you suggest something for me please

Very thankfull if you answer me

Hi Mukhalled,
The TDA1560 and TDA1562 ICs are the first "Class-H" circuits that I have ever seen! I wonder if you can hear them switch between Class-AB and Class-H, since they double the supply voltage during Class-H operation.
The TDA1560 has a guaranteed minimum output of only 27W with a reasonably low distortion, with an 8 ohm load. However, since most car speakers are 4 ohms, the TDA1562 is probably a better choice. It has a guaranteed minimum output of 45W with a reasonably low distortion, with a 4 ohm load.
That should be plenty of power to destroy your hearing and your "200W" little speakers!

Hello,

I am new to this site and my electronic knowledge stops back at high school.In this topic SASI refers to http://www.semiconductors.philips.com/markets/mms/products/analog/key_solutions/amplifiers/index.html
and
http://www.semiconductors.philips.com/acrobat/datasheets/TDA1560Q_4.pdf
Now if you go to the 2nd page where there is the datasheet of TDA1560Q there is a basic circuit on how to utilize the IC.If i build that circuit will it work or its mentioned for theoritical purposes?

Thank you in advance

Hi Atheos,
Welcome to our forum.
The schematic figure 6 on page 11 of the datasheet is complete and should work fine.
