ABSTRACT:
A feedback amplifier for providing an amplified signal to first and second utilization networks includes first and second feedback paths. The amplifier output is coupled via a first coupling resistor to a first terminal to which the first utilization network is connected, and via a second coupling resistor to a second terminal to which the second utilization network is subject to being connected. The first feedback path couples the amplifier output to the amplifier input exclusive of the first coupling resistor. The second feedback path couples the amplifier output to the amplifier input and includes the second coupling resistor. The amplifier output signal remains substantially constant in the presence or absence of said second utilization network.
