Re: the peripheral circuit of AD7278

Hello KarenNE,

       Do you think the AD7278 can work if I connect the peripheral circuit like the image I have attached above? What I wonder is that does the cs pin , sclk pin and the sddata pin need any pull-high resistor or capacity when be connected to the IO pins of FPGA?Or they can be connected to the IO pins of FPGA derectly? Thank you very much!!

         PS:I do think there's something wrong with the conversion results ,and I hope to conmunicate with you about that after I have a further study about it.

Thanks a lot.
