ABSTRACT:
Disclosed is an isolation amplifier, wherein a DC input signal is applied to the primary winding of a saturable reactor, the secondary winding of which is coupled with an oscillating circuit so as to supply the secondary circuit with a high-frequency current, and then the current flowing through the secondary winding is applied to a feed-back type low-pass filter, with which an output signal proportional to the DC input signal is extracted from the current flowing through the secondary winding.
