Filed: 1992-03-31
Abstract: PURPOSE:To facilitate compensation of offset voltage temperature characteristics of the entire sensor with a simple configuration by providing a differential operational amplifier circuit with a compensating circuit for adjusting the offset voltage at a chip stage. CONSTITUTION:A differential operational amplifier circuit consists of a bias circuit 31, a differential circuit 32 and an output buffer 33.

Therefore, by adjusting a resistor R13 through trimming, an input offset voltage is given. Since the temperature characteristics of the input offset voltage varies according to the magnitude of offset, the temperature drift of the offset as the entire sensor circuit can be compensated by giving an appropriate offset voltage.
