A differential output stage of an amplification device, for driving a load, comprises a first and a second differential output stage portion. The first differential output stage portion comprises: a first and a second output circuit; a first driving circuit comprising a first biasing circuit; a second driving circuit comprising a second biasing circuit. The first differential output stage portion comprises: a third output circuit connected between a first node of said first biasing circuit and a first differential output terminal, having a third driving terminal connected to a first driving terminal; a fourth output circuit connected between a first node of the second biasing circuit and the first differential output terminal, having a fourth driving terminal connected to a second driving terminal.
