PSoC 3/5 Del-Sig ADC Resolution and Sample Rate

Version 1
    Question: How does the resolution of the PSoC 3/5 Del-Sig ADC affect the sampling rate?

     

    Answer:

    Changing the Del-Sig ADC resolution directly affects the maximum/minimum sample rates possible in the ADC. The higher the resolution, the lower is the sample rate.

    The following table lists the maximum and minimum sample rate for different resolutions of the ADC.
