VOLTAGE DETECTING CIRCUIT

摘要

A voltage detection circuit includes: an amplifier having an inverting input terminal and a non-inverting input terminal, which amplifies a voltage difference between a first input signal input into the non-inverting input terminal via a first input portion and a second input signal input into the inverting input terminal via a second input portion; a first signal line which connects the first input portion to the amplifier; a second signal line which connects the second input portion to the amplifier; a first capacitor connected in parallel to the first signal line; a second capacitor connected in parallel to the second signal line; a first filter element which has an inductor component and a resistor component and is connected in series to the first signal line between the first capacitor and the amplifier; and a second filter element which an inductor component and a resistor component and is connected in series to the second signal line between the second capacitor and the amplifier.
