Abstract
A linear amplifier output stage is provided with unity gain buffer means having an input coupled to the output terminal and an output coupled to the stage input. The unity gain buffer means is normally turned off by a control signal. When the amplifier is disabled by switching its bias current off, the buffers are turned on so that the output stage input capacitance is charged or discharged via the buffer means in accordance with the output terminal signal. When a plurality of such amplifiers are commonly coupled to a signal line the off amplifiers cannot be driven into conduction by the operating amplifier's output signal.
