the AD936X ADC maximum input is 0.625Vpk, when calculated ADC input power, will use the below equal:
P=Vrms^2/50, which Vrms=0.625Vpk/sqrt(2);
the ADC input resistor really is 50 ohm? actually, the ADC input resistor usually equal to a few Kohm resistor, such as 1Kohm;
why not using the really ADC input resistor to calculate ADC input power?
