    Hi,



    The answer to this depends on how the device is being used.

    If the device is in single-shot conversion mode, then once the previous conversion completes, the next conversion could be started immediately. You would write to the configuration register to set the input channel and start the conversion.

    If the device is in continuous conversion mode, then you would change the channel for the device. The change occurs AFTER the conversion in progress completes. Then you would wait for the next DRDY indication to collect the data.
