AD7794 CHANNEL SWITCHING

Hello ;

 

  I am using AD7794  with external reference 2.5 volts; I am using channel 1 ; 2 ;3 and 4 for loadcell  ; where channel 5 and 6 for resistive POT reading .

For channel 1 to 4 the configurations should be bipolar with gain 128 ; where channel  5 and 6 will be used as unipolar with gain of 1 .

 

Is my connection ok ?

 

How  deos the switching between channels  with  chaging the mode from unipolar to bipolar and changing the gain from 1 to 128  settings  will effect my reading speed ?

 

Thank you in advanced
