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 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 LIS2L02AQ 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 using external capacitances. A self-test capability al- lows 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 extend- ing from -40 to +85 . The LIS2L02AQ 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 Robotics

LIS2L02AS4 General Description
The LIS2L02AS4 is a low-power two axes 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 of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.
The IC interface is manufactured using a standard CMOS process that allows high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics.
The LIS2L02AS4 has a user selectable full scale of ±2g, ±6g and it is capable of measuring accelerations over a bandwidth of 1.5kHz for all axes. The device bandwidth may be reduced by using external capacitances. A self-test capability allows to check the mechanical and electrical signal path of the sensor.
The LIS2L02AS4 is available in plastic SMD package and it is specified over an extended temperature range of -40°C to +85°C.
The LIS2L02AS4 belongs to a family of products suitable for a variety of applications: Mobile terminals Gaming and Virtual Reality input devices Free-fall detection for data protection Antitheft systems and Inertial Navigation Appliance and Robotics
