"Webresistor in series from the op amp to the load. But in the case of a SAR ADC the charge injection would still disturb the op amp and a path must be provided for the charge coming out of the ADC. This is done by placing a capacitor across the input of the ADC. Placing a capacitor across the ADC input creates a simple RC circuit in front of the ADC. " - Charge injection sar adc
