Bosch BMA580 Accelerometer

Bosch BMA580 Accelerometer is a small acceleration sensor ideal for compact hearables. The Bosch BMA580 (1.2mm x 0.8mm x 0.55mm) includes unique voice activity detection via bone conduction and advanced power-saving features. The device ensures the microphone is activated only when needed, conserving power.

 The BMA580 targets hearables with voice activity detection that features bone conduction. Bone conduction detects the vibration of the user's voice to wake the device from sleep for increased power savings.
