ABSTRACT:
Disclosed is a differential amplifier circuit in which attenuators are provided to the inverting input terminal and non-inverting input terminal of the differential amplifier, respectively, whereby the amplitudes of input voltages are attenuated so that the amplitudes may fall within a linear range of operation of the differential amplifier, and whereby the input voltages are set at an operating point of the differential amplifier.
