Product overview

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.

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 LSM6DSV16BX embeds advanced dedicated features and data processing for motion processing like the finite state machine (FSM), sensor fusion low power (SFLP), adaptive self-configuration (ASC), and machine learning core (MLC) with exportable AI features/filters for IoT applications.

The LSM6DSV16BX integrates a 6-axis IMU sensor with audio accelerometer features in a compact package (2.5 x 3.0 x 0.71 mm).
