Abstract
This relates to a transformer coupled isolation amplifier employing multiple primary and secondary windings to separate power supply currents from signal currents. An input section includes an input amplifier, a flyback modulator and a first flyback demodulator. An output section includes an output amplifier and a second flyback demodulator. A power section alternately provides a voltage and a high impedance to the transformer, which voltage is coupled to the input and output amplifiers via first and second primary and first and second secondary windings respectively for the purpose of providing positive and negative power sources to the amplifiers. The input demodulator is coupled to the output demodulator by third primary and secondary windings.
