2 DESCRIPTION
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°C to +85°C.
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
