Summary: | There is provided a two-wire transmitter capable of obtaining a signal reflecting a continuous change in a sensor signal, and in addition, facilitating a configuration or processing in a subsequent stage. The two-wire transmitter that outputs an analog voltage signal V3 based upon a sensor signal V1 to a transmission line N1 includes: an intermediate potential generation circuit (100) for generating an intermediate potential between the transmission line N1 and a transmission line N2; an operational amplifier (101) to which the sensor signal V1 and a feedback signal V2 are supplied; and a current source (102) for generating a current 13 flowing from the transmission line N1 to the transmission line N2, based upon a control signal output from the operational amplifier (101). In this situation, the control signal controls the operational amplifier (101) to equalize the sensor signal V1 and the feedback signal V2. |
