DESCRIPTION

The LIS2L02AQ is a dual-axis linear accelerometer 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 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 trimmed to better match the sensing element characteristics. The LIS2L02AQ has a user selectable full scale of Figure 2. Block Diagram

2g, 6g and it is capable of measuring accelerations over a maximum bandwidth of 4.0 KHz for both the X and Y axis. The device bandwidth may be reduced by using external capacitances. A self-test capability allows the user to check the functioning of the system. The LIS2L02AQ is available in plastic SMD package and it is specified over a temperature range extending from -40 C to +85 C. The LIS2L02AQ belongs to a family of products suitable for a variety of applications: Motion activated functions in mobile terminals Gaming and Virtual Reality input devices Virtual reality input devices Antitheft systems and Inertial Navigation Appliance Control and Robotics
