検出器。 The AC input is input to a clamp circuit consisting of a first capacitor and a diode, the output of this clamp circuit is connected to the positive input terminal of the differential amplifier via the first resistor, and this positive input terminal is connected to the second input terminal. While grounding through a resistor, the AC input is input to a third resistor, and the output of the clamp circuit is input to a second capacitor, and the output of the third resistor and the output of the second capacitor are connected to each other. is inputted to the negative input terminal of the differential amplifier through a fourth resistor, and the negative input terminal and the output terminal of the differential amplifier are further connected through a fifth resistor to form a feedback circuit. A level detector characterized in that the differential amplifier, the second capacitor, and the first to fifth resistors form a subtraction circuit to eliminate the alternating current component.
