I have developed a custom board for AD2S1210. This board works correctly.
1. The /reset pin of IC loads the supervisory circuit. Hence the /reset pin goes to 0V from 5V in few seconds after start.
2. When the /reset pin is forced high manually by applying the +5V supply, the system works. ( I have put the system on complete functional test for 45 min after doing this and the system works correctly).
Request for Solution:
1. What would have caused the failure of /reset pin only.
Thanks & Regards,
