2 Description
The LIS3L02AS4 is a low-power three axes 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 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 LIS3L02AS4 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 capac-
itances. A self-test capability allows to check the me-
chanical and electrical signal path of the sensor.
The LIS3L02AS4 is available in plastic SMD package
and it is specified over an extended temperature
range of -40°C to +85°C.
The LIS3L02AS4 belongs to a family of products suit-
able 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
