Description
The LSM6DSV16B is a system-in-package inertial measurement unit (IMU) featuring
a 3-axis digital accelerometer and a 3-axis digital gyroscope with dual channels
for processing acceleration and angular rate sensing 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 on separate
channels with dedicated configuration, processing, and filtering.
The motion tracking in high-performance mode runs at 0.6 mA and enables always-
on low-power features for an optimal motion experience.
The LSM6DSV16B embeds advanced dedicated features and data processing for
motion processing like the finite state machine (FSM), sensor fusion low power
(SFLP), and adaptive self-configuration (ASC).
