    Abstract: A circuit arrangement ( 10 ) for compensating for nonlinearities (NL 1 , NL 2 ) from analog/digital converters ( 15, 16 ) operating with different timing, having at least two analog/digital converters ( 15, 16 ) which are each clocked with different timing and which each have a predetermined nonlinear converter characteristic with integral nonlinearities (NL 1 , NL 2 ), and which accept an analog input signal (VIN) applied to an input ( 11 ) on the circuit arrangement and respectively convert it into a digital intermediate signal (Z 1 , Z 2 ); and having a multiplexer ( 22 ) which is arranged downstream of the analog/digital converters and which successively switches through the digital intermediate signals (Z 1 , Z 2 ) in order to produce a digital output signal (ZD) from the circuit arrangement ( 10 ); where at least one of the nonlinear converter characteristics of the various analog/digital converters ( 15, 16 ) is predetermined such that after the intermediate signals have been combined in the multiplexer ( 22 ) the integral nonlinearities (NL 1 , NL 2 ) in the various analog/digital converters ( 15, 16 ) essentially compensate for one another.
