AD7689 Circuit


I'm trying to interface and AD7689 to a Raspberry Pi but for some reason, I am not succeeding. I have fried a Raspberry Pi in the process so I'd like to make sure that the circuit I am using is ok. The smoke came out near the power port of the raspberry pi. If anyone could have a look at the attached image and let me know if they can spot any reason why it would break the Raspberry Pi I would be very much thankful.
