all the adc available and being routinely used have 8 to 16 inputs from analogue signals. It is necessary to know for some specific applications in medical field where signals vary from 1 micro volt to few Milli volts in amplitude and frequency ranges from 0.05 Hz to few kHz. The sampling of such complexx signals and storing them in digital form is always necessary but with limitations. Can we know which ADCs have such complex signal handling capability?
