Default The most powerful amplifier for my application

3 questions:

First:
I search for the most powerful amplifier in ONE package?
(I know that there is parallel and bridge modes but I want to know what is the reference of the most powerful amplifier.)

Second:
It is to build a 2*200W(without distortion) to 2*300W amplifier (for 200W speakers).

I thought: 2 TDA7293 in parallel and/or bridge mode.

Third:
Can I have 200W with 2*TDA7293 in parallel mode?

Default Expensive?....no way

They certainly are expensive...These amplifiers were ordered for a work engineering project that never came to fruition...My cost was a whopping 0$...... Bob C.

WOW!

700$ ?!?

It's very expensive for me!

I forgot to give you the price: up to 200 (so approximately up to 200$)

So, I probably chose 3*TDA7293 in parallel. (But what about the bridge mode?)

I took a look on the UCD modules, they are very interesting but can I bought them in France? or it is only by internet?


@ RCBandwidth: Have you got a diagram of a "HI-FI" application with the PA03? (I want only to know how we can do an application with this part) And how about cooling with this?

Thanks for your answers....

others?

You can add drv134 with two set of parallel 7293 chips.
