Description
The LSM6DSV16BX is a system-in-package inertial measurement unit (IMU)
featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope with triple
channels for processing acceleration and angular rate data for motion tracking
(user interface, device power management, 3D head tracking for gaming and an
enhanced audio experience) as well as vibration detection for bone conduction
along with Qvar sensing on three separate channels with dedicated configuration,
processing, and filtering.
