  • Isolation circuit
    Patent number: 4506230
    Abstract: An isolation circuit provides an isolation amplifier which receives an input signal and feeds a multiplexer switching circuit which is coupled to the primary winding of an isolation transformer. A pair of secondary windings are coupled to demultiplexer switching circuits for reconstructing the original input signal. One secondary winding is thereby used to produce an isolated output signal and the other is used to provide a feedback signal to the operational amplifier. The amplifier and switches are powered by isolated power supplies.
