<p>An amplifier having an operational amplifier (1), and in which an output terminal of an acceleration sensor (S1) is connected to the non-inverting input terminal of the operational amplifier (1) a leakage resistor (R1) is connected between a non-inverting input terminal and the reference voltage, a first capacitor (C1) and a first resistor (R2) are connected in series with each other between the inverting input terminal and the reference voltage, first and second voltage dividing resistors (R4, R5) are connected in series with each other between the output terminal of the operational amplifier (1) and the reference voltage, and a second resistor (R3) and a second capacitor (C2) are connected in parallel with each other between the connection point of the voltage dividing resistors (R4, R5) and the inverting input terminal, and the relationship C1 x R2 < C2 x R3 is satisfied. <IMAGE></p> |
