Analog-to-digital converter for converting an analog input signal which is present at a signal input (2a, 2b) and has a specific frequency bandwidth, into an offset-free digital output signal, having a subtracting amplifier (5), which subtracts an analog actuating signal from the analog input signal in order to generate an analog difference signal and amplifies the analog difference signal generated, an analog-to-digital converter circuit (18) having a high clock rate for converting the amplified analog difference signal into the digital output signal, a digital clamping circuit (24) for digital low-pass filtering of the digital output signal, and having a digital-to-analog converter circuit (49) for converting the digital output signal filtered by the clamping circuit (24) into the analog actuating signal.
