We are using AURIX SAK-TC364DP-64F300W AA MCU.

To interface analog voltage, we used RC filter between opamp output & MCU.

Are the following only points to be considered to interface with ADC? 

1. Cut off frequency to be considered while calculating the RC values.

2. ADC sink current should be limited as per datasheet limits.

3. ADC sampling frequency should be at least twice the highest input signal frequency (Nyquist theorem).

Any other points that need to be considered while calculating the RC values to interface ADC of AURIX?
