A circuit arrangement is provided for suppressing offset, offset drift, and 1/f noise during analog/digital conversion. The arrangement includes an analog/digital converter configured to convert an analog input signal into output data, an inverter configured to invert the input signal, a switching element connected upstream of the analog/digital converter and downstream of the inverter and configured to periodically change over between the input signal and the inverted input signal at a predefinable switching frequency, and a switchable negator circuit connected downstream of the analog/digital converter and configured to periodically negate the output data from the analog/digital converter at the switching frequency, the output data being negated when the inverted input signal is applied to the analog/digital converter. An analog/digital converter is also provided with suppression of offset, offset drift, and 1/f noise during analog/digital conversion. A gradient amplifier having a circuit arrangement or an analog/digital converter is also provided.
