    Hi  ,

    I would suggest trying the configuration given in the datasheet. Connect all SDO of the AD7980 to a single data in of the host and configure each chip select (CS) to low sequentially. Which…

  • Hi NathanT,

    Thanks for your reply,we have tested with 3 AD7980  to an SPI-cmpatible digital host. but there are some errors. would you mind giving the right timing diagram? By testing,the SDOs connected together can not get the right results. if seperated, it is ok. So it maybe somethings wrong,  Could you give the application example?

    Thanks.
