Hi!
I am using the PCM2903 ADC to digitize measurements. So my question is whether the digital output of the ADC is a digitalization of the Voltage (Volt) or the Power (Watt)?
Since these are not proportional: P = V*V / R

Hi Henrik,
Most ADCs (including the PCM2903) digitize voltage seen at the input. With a known input impedance, you could further calculate the power delivered to the ADC by measuring the digital data if you needed to.
