| Zusammenfassung: | A balanced amplifier (1) is provided with: a first operational amplifier (11) whose reverse-phase input terminal is connected to an input voltage source (30) and whose reverse-phase input terminal is connected to an output terminal of the first operational amplifier; a second operational amplifier (12) whose positive-phase input terminal is connected to the input voltage source and whose reverse-phase input terminal is connected to an output terminal of the second operational amplifier; and a voltage division circuit (20i, 20j, 20k, 20l) for dividing a reference voltage supplied from a reference voltage source (40), the reference voltage source being connected to a positive-phase input terminal of each of the first operational amplifier and the operational amplifier through the voltage division circuit. |
