Why is the linear temperature sensor a normalized output?
The so-called normalized output is that the sensor output voltage is limited to a small range at a temperature of 0 ° C under specified operating conditions. Even if not interchanged, the reference voltage value is limited to only 690-710 mV. In this way, in the circuit design, it is easy to grasp the output of the sensor in a macroscopic manner. Regardless of the bridge design or temperature compensation, as long as it is considered between 690-710mV, it can be adjusted slightly during debugging. Unlike ordinary thermistors, their resistance values are different depending on the model. Different design calculations are required for different models. Therefore, the standardized output of the linear temperature sensor can realize the standardized design of the instrument circuit.
