A voltage digitizer of the type in which the number of charge quanta that have to be applied to an integrating amplifier to balance the input voltage are counted is characterized in that both a fast acting and a slow acting feedback are provided. In Fig. 1, fast and slow feedback loops extend from the quantum generator QC over a resistor R4 and a resistor R6, respectively, and they function simultaneously. In a modification, Fig. 3, the fast and slow feedbacks function successively; for a first part of the measuring cycle large quanta at a slow frequency are applied over resistor R4 and for the remainder of the cycle small quanta at a high frequency are used.
