Magnetometer BMM350
High accuracy. Low-noise. Unique field shock recovery feature
Coming soon: BMM350
Magnetometer
Losing orientation? Say goodbye thanks to the BMM350 digital pathfinder. It gets everyone to their destination, enables tracking of head movements and thus 3D audio for a personalized sound experience. In the AR/VR area we take up the struggle against motion sickness with the reduction of pixel latency. The 16-bit 3-axis magnetometer can be used in wearables and hearables, smartphones and tablets, AR and VR, and various vehicles. It is almost invisible due to its enormously small size (1.28mm x 1.28mm x 0.5mm) and has 20 times lower current consumption compared to its previous generation. BMM350 impresses with highest accuracy and ultra-low noise. The BMM350 is based on innovative TMR (tunnel magnetoresistance) technology and includes a unique field shock recovery feature. This capability makes the device very robust against external magnetic fields, ensuring high accuracy at all times.
