The Amp for wich i will use it, is an aleph 5. When i put 2 capacitors in the + and the -, the noise dissapear.

Why is it not possible to drive the aleph direct by the drv134 ?

I cant see why you cant drive Aleph 5 or any other power amplifier
directly from DRV134.

About putting caps, I suppose you mean SERIES Output caps.
When you have not a stable DC output 0 Volt level (some dc-offset)
you may need output caps to get it to work well.

You can try without caps, and try different levels sound output
while measure any DC-Voltage at those two DRV134 outputs.
If you get any substancial DC-Offset output,
you should use Output caps.
