Claim:
1. An output stage adapted to operate in at least a first operating state and a second operating state, the output stage comprising: a first, a second, a third and a fourth configurable input/output terminals; and, a first, a second, a third and a fourth switches, each having a first main terminal, a second main terminal and a control terminal, the control terminal being adapted to receive a control signal for controlling the open or closed state of the switch, wherein, the first input/output terminal is connected to the first main terminal of the first switch; the second input/output terminal is connected to the first main terminal of the second switch; the second main terminal of the first switch is connected to the first main terminal of the third switch through a first branch, the second main terminal of the second switch is connected to the first main terminal of the fourth switch through a second branch; the third input/output terminal is connected to the first branch and the fourth input/output terminal is connected to the second branch; the second main terminals of the third and fourth switches are both connected to a common node receiving a reference potential; and, wherein, when the first and second input/output terminals are configured to operate as input terminals, the third and fourth input/output terminals are configured to operate as output terminals; and, when the first and second input/output terminals are configured to operate as output terminals, the third and fourth input/output terminals are configured to operate as input terminals; and, wherein, in the first operating state, the output stage is arranged in a first electrical configuration; and in the second operating state wherein the output stage is arranged in a second electrical configuration different from the first configuration.
