Different ADC input voltages result in varying current consumption of the chip

Hi

    Different ADC input voltages result in varying current consumption of the chip,Test as attached, is this normal？

Hi,

Are you experiencing power draw from the ADC which is higher than what is described in the SAADC Electrical Specification and the provided average current calculation formula below the table there?

Or, do you see power draw below those values for all measurements, but some are much lower?
