LIS3L02AS

The LIS3L02AS is a tri-axis linear accelerometer that includes a sensing element and an IC inter- face able to take the information from the sensing element and to provide an analog signal to the ex- ternal world.

The sensing element, capable to detect the accel- eration, is manufactured using a dedicated pro- cess 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 trimmed to better match the sensing element characteristics. The LIS3L02AS has a user selectable full scale of 2g, 6g and it is capable of measuring accelerations over a maximum bandwidth of 4.0 KHz for the X and Y axis and 2.5KHz for the Z axis. The device bandwidth may be reduced by using external ca- pacitances. A self-test capability allows the user to check the functioning of the system.

The LIS3L02AS is available in plastic SMD pack- age and it is specified over a temperature range extending from -40°C to +85°C. The LIS3L02AS belongs to a family of products suitable for a variety of applications:
    Antitheft systems
    Inertial navigation
    Virtual reality input devices
    Vibration Monitoring, recording and compen- sation
    Appliance control
    Robotics
