Zusammenfassung:In order to decrease a change in the offset caused by high-frequency noise, filter circuits for cutting high-frequency noise are inserted between the input terminals of a differential amplifier circuit and input nodes of a differential amplifier stage, the filter circuits having a cut-off frequency which is higher than a cut-off frequency of the differential amplifier circuit but is lower than a cut-off frequency of a parasitic filter circuit constituted by a parasitic capacity and a parasitic resistance in the input unit.
