Recently I had a full board using, among others, the chips named above. As I got ADA4004 or ADG1436 burnt without any explanation, I did a prototype board using only the above chips to try to discover the problem and still have the same problem: without any apparent reason, suddenly one or both chips got burnt. I have checked the pinout and everything seems OK. I dont see any reason for this....could anyone please check the schematic to check if there is something wrong?
I attache the schematic.
I am using a power supply to check currents althoug the schmatic is thought to use a ATX power supply.
Thanks un advance,
