The LIS3LV02DLTR 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 LIS3LV02DLTR 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 LIS3LV02DLTR is available in plastic SMD package and it is specified over a temperature range extending from -40°C to +85°C.
The LIS3LV02DLTR belongs to a family of products suitable for a variety of applications:Free-Fall detection Motion activated functions in portable terminals Antitheft systems and Inertial navigation Gaming and virtual reality input devices Vibration monitoring and compensation
