HJMAG804 is a dual-axis high-precision weak magnetic measurement module. This circuit consists of a constant current source, oscillation source, acceleration network, driving network, voltage doubling network, amplification network, synchronous modulation/demodulation network, integration network, force feedback network, bias circuit, and others. The inclusion of a force feedback network in the module allows the system to operate in a closed loop. Therefore, compared to traditional magnetoresistive sensors, the HJMAG804 circuit has advantages such as high detection accuracy, high reliability, good stability, high sensitivity, and high resolution for weak magnetic fields. It can be widely used in navigation systems, orientation determination, and weak magnetic field measurement.
