    I am working on AD6655 adc. i was able to cofigure it properly but from last 1 week i am struggling with it. I am using channel A, i can see Clock is comming at CLK pins(49,50) but DCOA is having lots of noise and drift.Previously, I was able to get DCOA without programing the device, but not now.
    
 
    Thanks in advnce??

      Hi,
      
 
      Can you please send a list of the SPI writes you are using to configure the AD6655?  Also, please verify that when you write to configure the device that the settings are being written properly (i.e. read back to verify that the settings are what you expect).
      
 
      Regards,
