HI,
   How the input peak to peak voltage range (not frequency) for conventional flash ADC is decided??.
If we dnt use sample and hold(S/H) , then whether is it decided by the supply voltage?? bcz without (S/H) there are no factors which limits the input voltage range i believe.
If we use (S/H) then,is inut range decided by (S/H) itself??
Or in both the cases are there any other factors too which decides input range??..


Thank you..
