An N bit flash ADC has 2^n comparators. When an unknown input Vin is applied to its input, all comparators whose reference voltage is less than Vin will give output 1 while others will give output 0. THe highest reference valued comparator is nearest to Vin. Thus a priority encoder will convert it to binary.
