Abstract
A device is provided for amplifying and sampling multiplexed analog signals so as to give them an optimum level before digitization thereof. It includes several amplification and sampling assemblies with fixed gains differing from one to another, an amplifier whose gain is able to take on several predetermined values, connection means for selectively connecting one of the assemblies to said amplifier, comparison means comparing the amplitude of the signals at the output of the amplifier with threshold voltages and a selection member for choosing the assembly and the gain of the amplifier as a function of the comparison. In each of the assemblies, the amplification function is provided either by amplifier stages and/or by sample and hold units.
