The present invention relates to an analog voltage-signal selector device of the type comprising at least one plurality of comparator circuits (Ci) operating in parallel and each having at least a first and second input terminals and designed to receive respectively an analog voltage-comparison signal (RAMP) and analog voltage signals (Vi) of predetermined value and at least one output terminal for digital voltage signals (Voi). This selector device 1 also comprises at least one logic circuit (L) having a plurality of input terminals each connected to a corresponding output terminal of the comparator circuits (Ci) and at least one output terminal. Finally said selector 1 incorporates at least one plurality of latches (Mi) each having at least one input terminal connected to the output terminal of a corresponding comparator circuit (Ci) and at least one drive terminal coupled to the output terminal of the logic circuit (L) with each of said memory circuits (Mi) having at least one output terminal corresponding to an output of the selector. <IMAGE>
