Hi, I'm trying to sampling a sinusoidal wave with frequency of 60Khz, put the ADC tooks about 7us to do one conversion. (using fadc = 24Mhz, continuos mode and only one channel enabled).
My question is: What's the minimum time between samples on ADC of STR912F?
8.33us / sample is the Nyquist limit, i.e. 120kHz sampling rate for a 60kHz input signal.
But that is the limit for measuring the amplitude and frequency of the input, i.e. to be able to recreate a 60kHz sinus signal with the same amplitude and phase. It will not be enough if you need to measure the waveform of a 60kHz signal (which implies that the signal is formed out of higher-frequency components).
