That all depends... You can free-run the ATMEGA chip ADCs at fairly high rates, see the controller's spec sheet for various clock options.
If you wish to do regular samples at a known rate, the TimerC component is usually limited to a 3ms min period. You can use other timers -- jiffyTimer, etal -- to go faster...but I have never seen any code posted that does this reliably... But it begs the question of what do you do with the data, since the Micaz can send around 100 29 byte messages a second. Search this list for audio, microphone, high frequency sampling for repeated discussions that have no final conclusions.
