After a New Channel is Selected  
the 1X speed mode the first conversion following a new  
speed, resolution, or channel selection is valid. Since  
there is no settling time between conversions, all 8 dif-  
ferential channels can be scanned at a rate of 500Hz.  
At the conclusion of each conversion, the converter is  
internally reset eliminating any memory effects between  
successive conversions and assuring stability of the high  
order delta-sigma modulator.
