Hello TJF, Thanks for your suggestion, to clarify my side further, let me elaborate.
My requirement is 256 (samples per Cycle) * 50(cycles, power frequency) * 6 (channels) = 76.8 k SPS So I need overall 100k(rounded off) 100k sampling. And my input signal is between +- 10 Volts and I don't want to scale for resolution purposes. Apart from that I need dedicated ADC for each channels so I'll prefer separate ADC chip. Does this make sense? Or I am wrong? Thanks On Friday, April 14, 2017, TJF <jeli.freih...@gmail.com> wrote: > Hi Rathin! > > Am Freitag, 14.
