Hello,

I would like to use the Kinetis K24F ADC for subsampling a signal. However, I cannot find the full-power bandwidth of the 16 bit ADC in the K24F specification.

Any idea where I can get this information ?

Thanks,

Hi Vincent,

Full-power bandwidth is defined as the frequency at which the amplitude of the digitized signal is decreased by 3 dB when the input is near the full scale amplitude. This is important for subsampling, where the input frequencies are above the sampling frequency. This is different from oversampling where we have to respect the Shannon-Nyquist rule, and it works as long as the signal is correctly band-limited and as long as the ADC does not filter out frequencies above the sampling frequency ! Thus my question...

I hope it is clearer now.

Thanks,

Jean-Luc

Hi Jean-Luc

What do you mean with full power bandwidth?
