I'm looking at a high common mode voltage difference amp (AD629). The input voltage between the two input pins next to each other will be 150VDC. Normally the pads should be bigger on the PCB than the actual pin size. So between these two pads is at most 0.6mm space.
I think this isn't enough. Do I have to make a cutout in the PCB? Why do the manufacturers design something like this? One or two NC-pins between the input pins would be very helpful. Thanks for your help.
