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
