LIS3L02DS

The LIS3L02DS is a tri-axis 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 to detect the acceleration, is manufactured using a dedicated process called THELMA (Thick Epi-Poly Layer for Microactuators and Accelerometers) 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 LIS3L02DS has a user selectable full scale of 2g, 6g and it is capable of measuring accelerations over a maximum bandwidth of 2.0 KHz for the X, Y axis and Z axis. The device bandwidth may be programmed 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/interrupt signal when a programmable acceleration threshold is exceeded along one of the three axis.

The LIS3L02DS is available in plastic SMD package and it is specified over a temperature range extending from -40°C to +85°C.

The LIS3L02DS belongs to a family of products suitable for a variety of applications:
   Antitheft systems and Inertial navigation
   Virtual reality input devices
   Vibration Monitoring, recording and compensation
   Robotics and Appliance control
