2 Description
The LIS3L02AQ3 is a low-power 3-Axis linear capac-
itive 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 accel-
eration, is manufactured using a dedicated process
developed by ST to produce inertial sensors and ac-
tuators 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 LIS3L02AQ3 has a user selectable full scale of

±2g, ±6g and it is capable of measuring accelerations
over a bandwidth of 1.5 KHz for all axes. The device
bandwidth may be reduced by using external capac-
itances. A self-test capability allows to check the me-
chanical and electrical signal path of the sensor.
The LIS3L02AQ3 is available in plastic SMD pack-
age and it is specified over an extended temperature
range of -40°C to +85°C.
The LIS3L02AQ3 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
