2 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 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°C to +85°C.

The LIS2L02AQ 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

– Virtual reality input devices

– Antitheft systems and Inertial Navigation

– Appliance Control and Robotics
