The AMC1200EVM board is working fine but one problem appears: the inputs from both amplifiers are not galvanic isolated from each other. The internal diodes made connection from VINP to VDD1 and from VINN to GND1. It should be a better design when each amplifier has it own 5Viso. No a can use only one channel from the board where I need two. But when you're not aware you can run in problems because J2 and J5 are connected to each others by the internal diodes and the common 5Viso.
