LIS2L02AS

The LIS2L02AS 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 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 LIS2L02AS 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 both the X and Y axis. The device bandwidth may be reduced by us- ing external capacitances. A self-test capability al- lows the user to check the functioning of the system.

The LIS2L02AS is available in plastic SMD package and it is specified over a temperature range extend- ing from -40 to +85. The LIS2L02AS belongs to a family of products suit- able for a variety of applications:
Antitheft systems
Inertial navigation
Virtual reality input devices
Vibration Monitoring, recording and compen-sation
Appliance control
