Any sample code available for AD7923, that could give complete picture for its operation?
I am sorry but we do not have available code for the AD7923. But I can recommend an alternative part AD7091R-4 which also a 12-bit ADC which ultra low power. An available code driver for the AD7091 can downloaded in the ADI wiki page . Are you still in the design stage of your application?
Yes please let me know the link for it.
You can check and download software driver from this AD7091 Wiki page link
