GT712 Hall Current Sensor

PublishTime：2023-12-20

●Summary: GT712 is a high-performance Hall effect current sensor that can more effectively measure AC (alternating current) or DC (direct current) current, and is widely used in industrial, consumer, and communication equipment. The GT712 series internally integrates a highly accurate and low-noise linear Hall circuit and a lowimpedance main current loop conductor. When the sampled current flows through the main current loop, the magnetic field it generates induces a corresponding electrical signal on the Hall circuit, which is then processed by the signal processing circuit to output a voltage signal, making the product output strictly proportional to the measured current value. The linear Hall circuit is manufactured using advanced BCDMOS process, which includes a high sensitivity Hall sensor, a preamplifier for the Hall signal, a high precision Hall temperature compensation unit, an oscillator, a dynamic offset elimination circuit, and an output module for the amplifier. In the absence of a magnetic field, the static output of the current sensor is 50% VCC. Under a power supply voltage of 5V, the sensor's static output can linearly change between 0.2~4.8V with the magnetic field, with a linearity of up to 0.4%. The dynamic offset elimination circuit integrated inside the GT712 ensures that the sensitivity of the sensor is not affected by external pressure and IC packaging stress. The GT712 is available in SOP8 package, with an operating temperature range of -40~150℃， and complies with RoHS standards.
