I need to sample 3 channels using the primary ADC. I need to refresh the three channels with a 10Hz frequency. I need CHOP. What should be the RC values in the input to reject 60Hz.
Basically you may use the dedicated settings for 60Hz in ADCFLT.
The input filter can support this further, but basically you only need a filter for the Sigma-Delta-Sampling rate (512ksps).
To calculate the filter this are basics for a simple RC-filter
f = 1 / (2 * R * C * PI).
So you may select the filter for your needs, but as a general recommendation you may use not to large values for R.
