It was right to connect the input coupling cap directly to pin 4 without any pulldown resistors.

Will you do another rev or is this the gotcha we need to be aware of?

You should beware of this until further notice. The X4 error is really important to notice but I will add a note in each shipment in case someone should miss this.

Has anybody tested my boards IRL yet?

i think operational amplifier is good in full balanced.

Thanks but this thread is only about my particular design.

I got inspired from someone (can you guess?) to make a DRV134 pcb with built-in regulators, two types of them and the discrete one can handle pretty high input voltage. The design comes right of my head and I haven't tested it in any way.

Do you have this PCB in Eagle format?
