HJMAG803A is a high-temperature three-axis high-precision weak magnetic measurement module. This circuit consists of an oscillation source, acceleration network, driving network, voltage doubling network, amplification network, synchronous demodulation network, integration network, feedback network, bias circuit, and temperature measurement circuit. It uses a magnetoresistive sensor circuit method to measure the geomagnetic field of the surrounding environment. The presence of the feedback network in the circuit makes it a closed-loop system; therefore, compared to traditional magnetoresistive sensors, the HJMAG803A circuit has advantages such as high detection accuracy, high reliability, good stability, high sensitivity, small zero position offset, and compact size. The module can operate at temperatures up to 180°C. It has been widely used in fields such as high-temperature oil logging, compass systems, navigation systems, and medical equipment. It achieves mutual conversion between geomagnetic signals and voltage signals.
