Acceleration sensor: BMA580
Smallest size. Unique speech processing. Highly flexible.
Acceleration sensor BMA580
Voice activity detection accelerometer
Stylish and minimalistic hearables offer little space for powerful components. The next-generation accelerometer with unique voice activity detection through bone conduction and advanced power mode features is the world’s smallest acceleration sensor (1.2 x 0.8 x 0.55 mm³). It is especially designed for compact devices such as hearables requiring the smallest components. BMA580 ensures that the microphone is turned on only if necessary to detect voice activity and save power.
Easy-to-integrate due to small size
Speech processing with integrated voice activity detection
Highly flexibility due to different power modes
