An analog/digital converter assembly includes a first analog/digital converter having N-bit resolution, operating by the parallel method and having comparators. A sample and hold element is connected upstream of the first analog/digital converter. A second analog/digital converter has M-bit resolution, operates by the parallel method and has comparators. A digital/analog converter is connected up-stream of the second analog/digital converter. A subtractor is connected to the digital/analog converter and to the sample and hold element. An amplifier is connected down-stream of the subtractor. Output signals of the comparators of the first analog/digital converter are provided directly with a 1X out of 2N code far triggering the digital/analog converter. The same reference voltage is applied to both the first analog/digital converter and the digital/analog converter.
