DIY Electroni dot com would like to show you about the 50 Watts stereo power amplifier
project with IC seriar TDA,It is TDA1514 ,I think,If you want to study about audio amplifier system,You might be start with the IC because you can apply it to many sound devices system such as.
-Middle subwoofer amplifier
-TV amplifier (NICAM® system or mono speaker)
-Surround Sound Amplifier
-computer speaker improvements, and other such as speakers with make in amplifiers
-For Hi End sound system projects this amplifier should also be used for mid-range or tweeter amplifiers in bi/tri amplifier systems.
Sure! We provides shcenmetic,PCB and componant list in this post.
They IC is worth the extra complexity (and is still very easy anyway). Other reasons why you would be to make this amplifier project are:
-Low harmonic and distortion
-Good thermal Protection
-Doesn’t click when switching on and off
-And from what I can tell, The amp has much better overall sound then TDA2040 chips (and the like).
-Able up to 50W of power amplifier.
They pictures below are PCB and print layout.
