ABSTRACT:
An amplifier (10) includes several output devices (12, 14), each of which is connected to a power source providing a different supply voltage. The inputs and outputs of the devices are coupled to the same signal input (V.sub.in) and output (V.sub.out). The device (12) operated from the lower supply voltage generates the lower level output signals and operates at a relatively high level of efficiency. When higher level output signals are called for, the device (14) operated from the higher supply voltage becomes active. The input of the lower level device is connected to the signal input through a circuit (16) which decouples the device input from the signal input when signals are present on the signal input which would force the device into saturation. The speed of operation of the amplifier is thus enhanced, since saturation of the lower level device (12) is prevented.
