AK09940

High Precision Tri-axis Magnetic Sensor

 Conventional tri-axis magnetic sensors have been used for position tracking applications. However, there are cases when sufficient performance is not possible due to magnetic field noise. World class ultra-low noise tri-axis sensing from the AK09940 resolves this problem, increasing magnetic position tracking accuracy for AR and VR.

 The AK09940 is ideal for magnetic particle testing and metal contamination detection with triaxial magnetic measuring, which measures wet field, small changes, and distortion in magnetic-fields with high precision. In addition, the AK09940 has very low power consumption current suitable for triaxial measurement in wearable and IoT devices with small batteries.

AK09940A

AK09940A is a digital output ultra-compact 3-axis electronic magnetometer that uses TMR magnetic sensor elements to achieve world-class ultra-low noise performance.

The magnetic field vector is output as an 18-bit digital value for each of the X, Y, and Z axes.

metal flaw or metal foreign object detection, as well, it might be able to be utilized in various fields magnetic detection has not been made.

AK09970D

Ultra-small Tri-axis Magnetic Smart Switch

 The AK09970D is an ultra-compact 3D magnetic smart switch with high sensitivity setting and high measurement resolution.

Key Features

Reduction of Package Area to 1/5 of Conventional ProductBy adopting a 1.35mm?, 6-pin WL-CSP package, the area has been reduced to an ultra-small size compared to the conventional 3.0mm?, 16-pin QFN package.Wide Measurement Range & High Resolution

The AK09970D has a high sensitivity setting of 36mT on tri-axis. It is able to measure a wide range of magnetic field from microtesla to millitesla such as from geomagnetic to a magnet since it has high measurement resolution of 1.1μT/LSB in high sensitivity mode. In addition, wide range setting of 101mT can be achieved via the Z axis.

AK09970N

Tri-axis Magnetic Sensor IC with Digital Output

Description

The AK09970N is a digital output 3D magnetic sensor that can select high resolution setting and wide measurement range setting.

The AK09970N has a high sensitivity setting of 36mT on tri-axis. It is able to measure a wide range of magnetic field from microtesla to millitesla such as from geomagnetic to a magnet since it has high measurement resolution of 1.1μT/LSB in high sensitivity mode. In addition, wide range setting of 101mT can be achieved via the Z axis.

Key Features

Low-power Consumption when Battery Life is Critical

The AK09970N can operate using only a few μA, thus consuming a very low current that satisfies a demand of IoT products, (Refer to the Specification Table). It contributes to a long battery life of a product that needs constant acquisition of sensor data to monitor an object’s status.

Magnetic Field Output (Digital)/ Data Ready alert (DRDY bit)

 The AK09970N measures magnetic field on all tri-axis via intermittent drive and outputs the result as digital data, (supporting I?C / SPI communications).

It outputs a Data Ready alert to the dedicated register when the measurement data is updated. (0.25 / 0.5 / 1 / 10 / 20 / 15 / 100Hz interval modes or single measurement mode is selectable for intermittent drive options.)

Magnetic Event Interrupt Function

 The AK09970N has magnetic event interrupt pins. Two thresholds can be programmed for each axis, (setting the resolution equal to the measuring resolution). When a magnetic field that exceeds the threshold is sent, the AK09970N outputs a “Magnetic Event” interrupt to registers or external output pins. The magnetic event that causes an interrupt output that can be selected freely by setting a register. (Data Ready alert mentioned in 3 can also be output from an interrupt pin). Two interrupt pins are available for magnetic event: the INT pin for push-pull output and the ODIN pin for open-drain output. Therefore, the output format can be selected depending on the customer’s product.
