An output of the amplifier is applied to a signal detector, wherein an output signal of the signal detector is an indication of an output power level of the optical receiver.

During the photoelectric conversion process of output signal from optical torque sensor, DC level drift error induced by temperature influence will affect the measuring accuracy of the system.

The multi-functional chip ADT14 is a kind of multi-point temperature monitor of outputting logic level control signal, It is also a kind of temperature sensor of outputting simulated voltage signal .
