Abstract
A signal amplifier device providing output power independent of change in output characteristics or common mode interference including a signal input source to provide an input signal, a first power supply and second power supply having a transformer with a secondary coil and a reference power, first differential amplifier powered by the first power supply to receive the input signal and provide first and second complementary output signals, first and second output amplifiers driven by the reference power supply and each having an input to receive one of the first and second signals and amplify same to provide first and second output signals at the respective outputs so that upon imposition of a transient signal at the output of one of the first and second output amplifiers an isolation network prevent the transient signal from appearing as a differential signal on either output.
