Abstract
The voltage corresponding to the pressure outputted from a Wheatstone bridge having resistors R to R is amplified by a differential amplifier and operational amplifiers OP , OP , and then outputted through an output terminal to an external device as the output voltage VOUT. The offset voltage ZSOUT is outputted from the operational amplifier OP . The output voltage VOUT and the offset voltage ZSOUT are fed back to the reference source voltage Vsen by operational amplifiers OP to OP . In consequence, a non-linear output property of output-attenuating or output-increasing type can be easily obtained, while errors due to the offset voltage ZSOUT can be diminished.
