TDA7294 Stereo/Bridge with PSU

[apexaudio]

I dont like TDA7294, but this work OK. Easy to bridge. Anybody interesting this PCB?

Hi, thanks a lot for this circuit, did you have list of elements and it is already bridged? If not how to do that simply? Possibly that i am going to do this one

 

[CharlieLaub]

parallel TDA7293 PCB wanted

Any chance that you would develop a PCB for a 2 or 3 paralleled TDA7293s using the Master/slave connection shown in the datasheet? I would be ready to buy several of them...

I have PCB with TDA7293 mono without PSU, and I will develop paralleled version based on that circuit.
For paralleled circuit LM3886 is better choice.

The parallel TDA7293 using the master/slave is better I think. There is no need for resistors on the output to balance the load when using a slaved second amplifier.

You right, and is simplier.

Did you find PCB for TDA7293 in parallel?

 

[CharlieLaub]

Did you find PCB for TDA7293 in parallel?

Yes, I was able to go in on a batch of "2xTDA7293 in parallel" boards with someone. Did you develop one also?

No, I like see pcb for parallel TDA7293, but I prefer descrite amps for higer power, and hibryd (OP+transistors) also,

OK I am try!

Some time ago I also did the TDA7294 (of course not as perfect as it did APEXAUDIO) had good sound but had a channel noise and the other not, was a lack of GND
Of all that makes it sounds like he did

 

[uly5ses]

Also you do with that software is seen to be very professional

Nothing is perfect on my TDA7294 design, but work well.

You have the schematic? sorry if this poorly translated

 

[uly5ses]

entonces se acerca a la perfeccion

 

[planet10]

then approaches perfection

stereo to mono converter circuit

hi everyone. kind of new here. Sir apex, if i understood it correctly, this circuit is a stereo to mono converter right? but it looks complicated and some parts looks like hard to find like TDA __? Im really in need of a circuit that converts our OP amps to mono bridged configuration, that is, safely. thanks!

This is stereo amplifier, and it can be simple bridged to mono with double power.
