I have a circuit where I measure a fairly fast signal (1Mhz in frequency) using ADC. The signal is fed to the ADC using an Opamp, however there is no RC filter following the Opamp to the ADC, I didn't know about the need for such charge capacitor holder. Currently, Opamp output is directly connected to the ADC pin.
Anyway, now my system works, what are the down sides of not having this RC circuit there? If I add this RC circuit, what would be the benefits.
