Ask Questions about ADL5391

Hi,

Now one customer downloaded the gerber file of the ADL5391 Evaluation board and then made a PCB board. All the  components which listed in the datasheet were soldered on the board.

Keep all the input and output channels floating, then power up the board, we found that the ADL5391 can be damaged easily. Because there is no user guide of the EVM board. I want to know why and how to use this board correctly.Would you please give me some suggestions?

Thanks!
