AMC1200EVM / J2 and J5 inputs not isolated to each other!!

Other Parts Discussed in Thread: AMC1200EVM, AMC1200

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.


Best regards,
