发明名称 Interface circuit
摘要 A circuit for interfacing with the outputs of a differential pressure sensor provides a single-ended output voltage translated in voltage level with respect to the differential voltage applied thereto from the sensor while cancelling the common mode offset voltage of the sensor so that the output voltage is independent of the common mode offset voltage. The circuit includes four operational amplifiers arranged as a differential-to-single ended converter with gain.
