Abstract: |
|||
| The present invention discloses a precision isolated amplifier, it includes gain control circuit formed from key switch, anti-static flutter-removing circuit, circulation control state generation circuit and switching circuit which are successively connected; preamplifcation and filter circuit composed of input protection circuit, buffer circuit and at least two-stage amplification and filter circuit which are successively connected; and isolated amplification and output filter circuit formed from output filter and buffer circuit and isolated amplifier circuit which are connected. The switching circuit is respectively connected with every-stage amplification and filter circuit, the input end of the final-stage amplification and filter circuit is respectively connected with isolated amplifier circuit and over voltage detection indication circuit. | |||
