The LIS3LV02DL is a three axes digital output linear accelerometer that includes a sensing element and an IC interface able to take the information from the sensing element and to provide the measured acceleration signals to the external world through an I²C/SPI serial interface.

The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.

The IC interface instead is manufactured using a CMOS process that allows high level of integration to design a dedicated circuit which is factory trimmed to better match the sensing element characteristics.

The LIS3LV02DL has a user selectable full scale of ±2g, ±6g and it is capable of measuring acceleration over a bandwidth of 640 Hz for all axes. The device bandwidth may be selected accordingly to the application requirements.

The self-test capability allows the user to check the functioning of the device.

The device may be also configured to generate an inertial wake-up/free-fall interrupt signal when a programmable acceleration threshold is crossed at least in one of the three axes.

The LIS3LV02DL is available in plastic SMD package and it is specified over a temperature range extending from -40°C to +85°C.

The LIS3LV02DL belongs to a family of products suitable for a variety of applications:Free-Fall detectionMotion activated functions in portable terminalsAntitheft systems and Inertial navigationGaming and virtual reality input devicesVibration monitoring and compensation
