Note
（1）The output voltage Uout , the offset voltage UQOV , and the sensitivity Gth are completely proportional to the power supply Vc.
（2）The frequency of the current to be measured needs to be limited within the frequency band of the sensor, otherwise the core and chip will be overheated.
（3）Incorrect wiring can damage the sensor.
