Abstract
A multi-input differential amplifying device of the present invention includes: a differential amplifier having an inverting input terminal and a non-inverting input terminal; and an input portion configured to apply a first input voltage to a first input terminal that is one of the inverting input terminal and the non-inverting input terminal and apply a second input voltage to a second input terminal that is the other input terminal, the first input voltage corresponding to first input signals that are a plurality of input signals for the first input terminal, the second input voltage corresponding to a second input signal that is one input signal for the second input terminal. The input portion is configured to correct an offset voltage between the first input voltage and the second input voltage.
