The LIS3L02AQ is a low-power three-axis linear ac- celerometer that includes a sensing element and an IC interface able to take the information from the sensing element and to provide an analog signal to the external world.
The sensing element, capable to detect the acceler- ation, is manufactured using a dedicated process called THELMA (Thick Epi-Poly Layer for Microactu- ators and Accelerometers) developed by ST to pro- duce 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 LIS3L02AQ 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 band- width may be reduced by using external capacitanc- es. A self-test capability allows the user to check the functioning of the system.
The LIS3L02AQ is available in plastic SMD package and it is specified over a temperature range extend- ing from -40 to +85. The LIS3L02AQ belongs to a family of products suit- able for a variety of applications:
Motion activated functions in mobile terminals Gaming and Virtual Reality input devices Free-fall detection and Data protection Antitheft systems and Inertial Navigation Appliance Control and Robotics
LIS3L02AQ Maximum Ratings
Stresses above those listed as "absolute maximum ratings" may cause permanent damage to the device. This s a stress rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
