In an arrangement for conversion of an analog acquisition signal of an acquisition coil of a magnetic resonance apparatus into a digital signal, the output of the acquisition coil is connected with a low-noise amplifier such that the analog acquisition signal from the acquisition coil arrives at the amplifier. The amplifier is connected at the output side with a device for analog-digital conversion, such that the analog acquisition signal arrives at the device for analog-digital conversion as an amplified acquisition signal for analog-digital conversion. The device for analog-digital conversion is designed as a delta-sigma modulator that forms a digital data stream with a width of one bit from the amplified acquisition signal.
