A fully differential amplifier device includes a first input and a second input, a first output and a second output, and a differential input stage, provided with a first input transistor and a second input transistor. The first input and the first output and the second input and the second output are directly connected selectively in a first operating configuration and disconnected in a second operating configuration. The amplifier device further includes a current-generator circuit connected so as to supply respective first currents to the first and second outputs irrespective of a state of conduction of the first and second input transistors.
