An apparatus for reading out a differential capacity with a first and second partial capacity includes a first oscillator having a first frequency-determining element connectable to the first partial capacity and a second oscillator having a second frequency-determining element connectable to the second partial capacity; a switching means to switch the first frequency-determining element into a first state or to switch it into a second state, and to switch the second frequency-determining element into a third state or to switch it into a fourth state; read apparatus having a first detection means connected to the first oscillator; and an evaluation means which carries out a quotient formation to obtain a value indicating a quotient of the first and the second partial capacity.
