The XBLW GT712 is a high-performance Hall-effect current sensor that can measure alternating current (AC) or direct current (DC) more efficiently for a wide range of industrial, consumer and communications devices.

The GT712 series integrates a high-precision, low-noise linear Hall circuit and a low-impedance main current loop wire. When the sampling current flows through the main current loop, the magnetic field generated by it induces the corresponding electrical signal on the Hall circuit, and the voltage signal is output through the signal processing circuit, so that the output of the product is strictly proportional to the measured current value.


The linear Hall circuit is produced using an advanced BCDMOS process, which includes a high sensitivity Hall sensor, Hall signal pre-amplifier, high precision Hall temperature compensation unit, oscillator, dynamic offset cancellation circuit and amplifier output module. In the absence of magnetic field, the static output of the current sensor is 50%VCC. Under the condition of 5V power supply voltage, the static output of the sensor can change linearly with the magnetic field between 0.2~4.8V, and the linearity can reach 0.4%.
