描述MEMS digital output motion sensor:high-performance ultra-low-power 3-axis "femto" accelerometer
产品概述

描述

The LIS2DW is an ultra-low-power, high performance three-axis linear accelerometer belonging to the “femto” family which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers.

The LIS2DW has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz.

The LIS2DW has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor.

The embedded self-test capability allows the user to check the functioning of the sensor in the final application.

The LIS2DW has a dedicated internal engine to process motion and acceleration detection including free-fall, wakeup, highly configurable single/double-tap recognition, activity/inactivity, stationary/motion detection, portrait/landscape detection and 6D/4D orientation.

The LIS2DW is available in a small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
