Features
Description
The LIS344AL is an ultra compact consumer low-
power three-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 of detecting the
acceleration, is manufactured using a dedicated
process developed by ST to produce inertial
sensors and actuators in silicon.
The IC interface 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.

3-axis ultracompact linear accelerometer
Rev 1
The LIS344AL is capable of measuring
accelerations over a maximum bandwidth of
2.0kHz. The device bandwidth may be reduced by
using external capacitances. A self-test capability
allows the user to check the functioning of the
system.
The LIS344AL is available in Land Grid Array
package (LGA) and it is guarantee to operate over
an extended temperature range of -40°C to
+85°C.
The LIS344AL belongs to a family of products
suitable for a variety of applications:
– Mobile terminals
– Gaming and virtual reality input devices
– Antitheft systems and inertial navigation
– Appliance and robotics.
