TDA7294 Stereo/Bridge with PSU

apexaudio · 26th February 2010, 07:43 PM

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

PCB size: 115x62,5mm

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

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?

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