Product overview

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).

The LSM6DSV16B integrates a 6-axis IMU sensor with audio accelerometer features in a compact package (2.5 x 3.0 x 0.71 mm).
