Description
The LIS331AL is the smallest 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.
The LIS331AL 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 LIS331AL is available in Land Grid Array
package (LGA) and it is guaranteed to operate
over an extended temperature range of -40°C to
+85°C.
