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 LIS3LV02DQ 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. A self-test capability allows the user to check the functioning of the system The device may be 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 LIS3LV02DQ is available in plastic SMD package and it is specified over a temperature range extending from -40°C to +85°C. The LIS3LV02DQ 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 QFPN-28 Order codes Part number Op.
