May me TI but how much bit & channel u required.

Re: Fastest ADC & its Conversion

There is multi-channel ADC ICs, bit resolution depends from project needs. Also you can use separate ADC IC for each channel.

Flash ADC is the fastest method of conversion. But it has demerits. it requires much opamps.

for 8-bit conversion we need 255 opamps. which is impossible to construct. where would you place this freaky circuit just for 8 bit. so this is the major disadvantage of the flash adc.

Re: Fastest ADC & its Conversion

The fastest ones, you'll probably never see; indium phosphide
stuff in fairly narrow flash architectures was running 30+ GSPS,
five years ago. Northrop Grumman and NTT and folks like that
doing their own ICs in their own fabs for in-house consumption.
