Preliminary Technical Data
FREQUENCY RESPONSE
The sigma-delta modulator runs at the MCLK frequency,
which is effectively the sampling frequency. Therefore, the
modulator Nyquist frequency is of the MCLK.
Rev. 0 | Page 28 of 32
If chopping is enabled, the input signal is resampled by
chopping. Therefore, the overall frequency response features
notches close to the frequency of 1/channel conversion time.
The typical ADC frequency response plots are given in
Figure 26 and Figure 27. The plots are normalized to 1/channel
conversion time.
Note that these figures apply to each channel separately and are
based on individual channel conversion time. The signal is
effectively resampled once more in the multiplexer by switching
between enabled analog inputs.
