Common-mode voltage reaches + 1000V Differential amplifier circuit with INA110
As shown in figure, the circuitis common-mode differential amplifying circuit with the input voltagebeing+ 1000V. This circuit adopts mosfet (FET) input apparatus using amplifierINA110 and input resistance bleeder. Reverse phase input and in-phase input is respectivelycomposedof R1, R2 and R3, R4.Because R1=R3, R2=R4, the attenuation ratio of voltage divider is: K=R2/(R1+R2)=10/(10+990)=1/100.
