AD7470 acquisition time

The Data sheet for AD7470/AD7472 says acquisition time is *minimum* 135[ns]  in "Specification" section and then in the "Timing Specfications" section says this number is a max. I assume this is an error or am I missing something?

    Hi Hoser519,

       Sorry for the much delay. That should be the minimum acquisition time as the mentioned in the DC acquisition section, there is a settling time requirement that last 135ns which also the acquisition time. This should make the minimum requirement of 135ns after an end of conversion should the AD7470 acquire the new sample.

    Regards,

    Jonathan
