Abstract

An analog-to-digital converter circuit has pre-sample and hold circuit for acquiring and temporarily storing a supplied analog input signal, and for outputting the temporarily stored input signal, at least two signal paths, which are arranged downstream relative to the pre-sample and hold circuit and which are switched in parallel with one another, the temporarily stored input signal sample from the pre-sample and hold circuit being subjected to respective fixed amplifications, which are different from one another, in said signal paths and a selection circuit arranged downstream relative to the signal paths for through-connecting only one of the signal paths, dependent on the respective signal levels, to an analog-to-digital converter that is arranged downstream relative to the selection circuit.
