AK8980

Introduction: The AK8980 is a 3-axis magnetic field sensor containing a semiconductor magnetoresistive element developed by Asahi Kasei Microdevices Corporation. The AK8980 can be used to measure the magnitude and direction of a magnetic field and convert it into a voltage. It is widely used in a variety of applications, from consumer electronics to automotive systems, for magnetic field detection and measurement. This article will describe the application field and working principle of the AK8980. Application Field: The AK8980 can be used in a variety of applications, such as consumer electronics, automotive systems, medical applications, industrial and security systems, satellite orientation, robotics, and navigation systems. Consumer electronics applications include the detection of magnetic fields and interference in televisions, DVD players, game consoles, and electronic magnifiers. In automotive systems, the AK8980 is used for windshield wiper orientation, door latch lever position sensing, HVAC (heating, ventilation, and air conditioning) control, and airbag control in automobiles. Medical applications include the detection of magnetic fields in diagnostic instruments and implants, such as pacemakers. Additionally, it can be used in industrial and security systems for static magnetic field detection and real-time detection of changes in magnetic fields. Furthermore, the AK8980 is used for satellite orientation and navigation systems, as well as robotics, for the detection and measurement of magnetic fields. Working Principle: The AK8980 contains anodes, magnetic field-sensitive magnetoresistive elements used to detect magnetic fields and convert them into an output voltage. The AK8980 has a sensitivity of 0.7V/mT (milliTesla) and an upper limit of ±75mT for detecting static magnetic fields. It can detect parameters such as magnetic field strength, direction, and changes in the intensity of the magnetic field. The AK8980 is a 3-axis device, meaning that it can detect magnetic fields in three directions: X, Y, and Z. It is composed of a three-axis magnetoresistor, a three-axis switching amplifier, and a three-axis ADC (Analog to Digital Converter). The three magnetoresistors are arranged at a 45-degree angle from each other in an X-Y-Z plane. The magnetic field is detected individually by each magnetoresistor and its output is amplified. The output signals of the switching amplifiers are then translated into digital form via the ADC and transmitted to a microprocessor or microcontroller. The AK8980 can measure fields up to a maximum frequency of 10kHz and can be used in both static and dynamic measurements. The device is also designed to optimize power cause and low-noise operation. The output signals can be set as either a digital signal (SPI/I2C bus) or an analog signal (low impedance). For analog signals, the device is configured to output a voltage range of 0V to 4.096V (maximum).Conclusion: The AK8980 is a 3-axis magnetic field sensor that is used in a variety of applications to detect and measure static and dynamic magnetic fields. It is composed of a three-axis magnetoresistor, a three-axis switching amplifier, and a three-axis ADC, and features a sensitivity of 0.7V/mT and an upper limit of ±75mT for static magnetic fields. Additionally, the device is configured to output a voltage range of 0V to 4.096V (maximum) for analog signals and can measure fields up to a maximum frequency of 10kHz.
