Hi Pradeep,

Your configuration looks good to me. Does your circuit have any connection between GND_ADC and GND ground?

BR,

Dale

Hi,

Thanks for the response. No, I am not having any connection between GND_ADC and GND.

Hi found that the issue was due to the Sync# ping. we need to keep the Sync# pin high in-order to have the conversion started. When i made the Sync# pin high, DRDY signal started coming. Thanks for your response.
