ISOLATION AMPLIFIER
An isolation amplifier is of various uses. It can separate a signal from a DC level different part and detect a signal in abnormal voltage change. It operates as follows: 1) an arbitrary input is amplified by an amplifier (2). 2) Its output is supplied to difference amplifiers(3,4) with off-set volt...

| Zusammenfassung: | An isolation amplifier is of various uses. It can separate a signal from a DC level different part and detect a signal in abnormal voltage change. It operates as follows: 1) an arbitrary input is amplified by an amplifier (2). 2) Its output is supplied to difference amplifiers(3,4) with off-set voltage. 3) The output of difference amplifiers are supplied to photo-couplers(6) whose output is changed linearly. 4) And two output of photo-couplers is added in adder(8). 5) Thus the input signal is amplified without distortion. |
