Really enjoy these and the more detailed versions on the web site. I'm curious of this and the last amp, just because I haven't built them.... yet. :-) How hot would the TDA2003 chip get with a less substantial heat sink? I would love to build the single ended amp but the heat sink size is holding me back a bit. Any thoughts here... Thank you very much for your time and efforts!
I'm going to visit the EasyEDA to sign up. Q: that site does/doesn't do PCB component placement and/or autorouting? Your presentation was balanced, informative and interesting. I wish I had a pile of heat sinks like the one shown. Thx.
This is just a power stage with no voltage gain(in a current gain configuration). It could be used that way, but that isn't the way he purposed the chip. The volume would be controlled in a preamp or from the source, all this does is give that signal enough current backing it to drive speakers. You could run your signal through a pot first though, nothing is stopping you from doing that.
interesting points ,if anyone else wants to learn about how to make electronic circuits try Sovallo Circuits Expert Fixer (do a google search ) ? Ive heard some awesome things about it and my mate got great success with it.
Do you hear any high frequency rings coming from the speakers even when the audio source is plugged in? The current amplifier I use for my speakers has this problem. Its quiet enough to stand but definitely annoying. I'm considering making this, but with a few improvements for bass response and such to replace my current amplifier as it will be both practical and fun to make.
How did you determine C4 and C12? I see 470u caps to remove DC offsets on the output and that has always seemed to do the trick. Did you use 1000uF for any specific reason? I understand that the higher the capacity, the lower the frequency response, but that means if the capacity is too high, it will take longer to remove any DC offset on the output. The dreaded *THUNK* if you power the amp already plugged into speakers. Just trying to figure out the way to determine the capacity to use. Also, can you explain the logic of the feedback capacitor? Wouldn't that add delay to the feedback? Is it just to stiffle high frequency oscillation, or does it have to do with the fact that the feedback needs to be DC offset since the negative rail is grounded(single rail supply).
My copy of this circuit does not like the resistor R9. It seems to induce clipping + noise to the low voltage swing of the output. Any ideas way that would be the case?
hi, you do an amazing job but unfortunatelly people like me is very hard to find a way to print the schematics and print. why you dont just print a simple ironing schematic i can print please thanks...
'Power opamps' are strange beasts, as they aren't actually opamps at all, but rather more like an op amp driving some transistor power stage(the kind of transistor depends on the power opamp). Because of the complications this poses in modeling, you are going to have a hard time finding an accurate model.
The C1 coupling audio signal through the VR1 to adjust the volume. Then sent to the C2 anti-noise DC input signal to pin 1 of IC. The non-inverting amplifier circuit is a non-return phase. This is the signal output pin 4, by a C5 enhances the stability of low-frequency response the better
Video great, Thanks for this tutorial Sir!

Very well done presentation.

great video! I would add volume control. Why you didn't?
Thanks for sharing knowledge of designing pcb.
I'll try to create something with TDA2005.

Make one stereo amplifier using tda2030

Nice

Nice!
How to stop the humming noise when no source is connected? ?
Ügyes, szép megoldás, de azért a bemenetre egy sztereó 50 K A potmétert kellene kötni a bemeneti zaj miatt
How can I run a simulation? I tried but nothing shows up
Do you know what simulator i can use to simulate TDA2003?
Thanks.

how much watt the speakers?
Hey bro Its AMazing PLz mAke a Tda2030 Stereo CIrcuit And Give me the Layout
Can i use 16v Capacitors instead of 25?
No
I'm sorry my English, I don't understand C2 470uF doing?

show audio amplifier video
Your only limit of going higher is your 400ma supply
