摘要：A power amplifying circuit includes first and second operational amplifiers. Thepower amplifying circuit includes first to fourth feedback resistor. The power amplifyingcircuit includes a fully differential operational amplifier that is connected to the outputterminal of the first operational amplifier at a non-inverting input terminal thereof, to the

output terminal of the second operational amplifier at an inverting input terminalthereof, to a first signal output terminal at a non-inverting output terminal thereof, andto a second signal output terminal at an inverting output terminal thereof and maintainsa constant differential gain. The power amplifying circuit includes a switching circuit. Thepower amplifying circuit includes first and second input resistors. The power amplifyingcircuit includes a midpoint potential controlling circuit that monitors a power supplyvoltage and controls the switching circuit.
