摘要:
A voltage detection circuit includes: an amplifier which amplifies a voltage difference between first and second input signals input into non-inverting and inverting input terminals of the amplifier via first and second input portions; 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 has an inductor component and a resistor component and is connected in series to the second signal line between the second capacitor and the amplifier.
