Does anyone know where I can Buy a DRV PCB?

thx

Member digi01 sells one. I believe you get 4 PCB shipped for $22; not too bad.

Thanks!

I have made a DRV134 pcb.

The difference from Zang's board is that I have a "full" connection of the DRV134 and also the possibility to have rather high supply voltage. There is also room for a big audiophilic input cap.

If you need drv134 to bridge two amplifier boards, forget it. You must go for a bridging adapter or transformer. If you need it to get a balanced output, go for drv134. I test drv134 and that1646 for a bridge configuration and the result is lot of noise. Even assemblycraft.com have a bridge module to improve drv134:

What do you mean exactly?

What is a bridging adapter vs DRV134?

What is "lot of noise"? Is this noise you hear or measure?

I've used DRV134 for bridging amplifiers in a few implementations and have never noticed any noise problems; not even when used with a single supply.

The DRV134 has very little noise and also a high common mode output impedance otherwise it will do the same thing as an inverting opamp. The positive thing about this IC is that both halves of the amp will be driven from a good source.
