Magnetic sensors, a type of transducer, are utilized for a variety of functions, ranging from indicating the presence of a magnetic field to position and speed sensing. The AK09916C is an entry-level, low-power 3-axis magnetic sensor and is ideal for measuring small magnetic fields, such as those generated by the Earth’s magnetic field. The AK09916C is a linear magnetic sensor that can detect a wider range of magnetic fields compared to compass (IC) sensors due to its ability to detect up to 0.3 micro tesla. The primary application fields for the AK09916C are portable electronics, automotive applications, and magnetic shielding applications.

The AK09916C is an integrated circuit (IC) magnetic field sensor with two sensing elements capable of detecting magnetic fields in the X, Y, and Z axes. The IC’s three-axis magnetic sensing elements are extremely sensitive and can detect magnetic field strengths up to 0.3 micro tesla, one of the highest sensitivity levels available in the market. Each of the three magnetic sensing elements can sense magnetic fields in three different directions independently, allowing the AK09916C to accurately measure a wide range of magnetic field strengths and directions. The IC is based on an advanced Hall element sensing technology and utilizes a high-performance ASIC to ensure high accuracy and low noise.

The working principle of the AK09916C involves measuring the change in voltage as the magnetic field strength and direction changes. When the magnetic field changes, the sensing element of the IC increases or decreases its output voltage accordingly. This output voltage is then measured and combined with parameters such as gain, offset, temperature coefficients, and others to be used for further analysis. This analysis can be used to determine the direction and strength of the magnetic field. The AK09916C provides a digital output for easy integration with microcontrollers and hosts. It also has a built-in temperature sensor that allows the IC to operate in both hot and cold environments.

The AK09916C is a powerful and versatile 3-axis magnetic sensor ideal for a wide variety of applications. Its low power consumption and high accuracy makes it ideal for portable electronics, automotive applications, and magnetic shielding applications. Its advanced Hall element sensing technology and high-performance ASIC ensure accurate measurements in a wide range of environments. Due to its ability to measure extremely small magnetic fields, the AK09916C is also ideal for applications in geomagnetism and robotics.
