Hi,
The output data clocked for the AD7266 is for the current conversion. You can see this in figure 31 on page 17 of the AD7266 datasheet where the SGL/DIFF pin is set for both the acquisition and conversion time. The no pipeline delay feature only means that the conversion results are available immediately after the conversion is complete. I don't think there is a general keyword for our parts where conversion data for the conversion is output on the same cycle though. This is specified per datasheet.
Can you share what other specifications you require for your application so i can help you choose your part?
Regards,
Karen
