2 Description
The LIS2L02AS4 is a low-power two axes 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 of detecting the ac-
celeration, is manufactured using a dedicated pro-
cess developed by ST to produce inertial sensors
and actuators 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 LIS2L02AS4 has a user selectable full scale

of ±2g, ±6g and it is capable of measuring acceler-
ations over a bandwidth of 1.5kHz for all axes. The
device bandwidth may be reduced by using exter-
nal capacitances. A self-test capability allows to
check the mechanical and electrical signal path of
the sensor.
The LIS2L02AS4 is available in plastic SMD pack-
age and it is specified over an extended tempera-
ture range of -40°C to +85°C.
The LIS2L02AS4 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
