Description
The LIS332AX is an ultracompact low-power 3-
axis linear accelerometer that includes a sensing
element and an IC interface 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 a high level of integration to
design a dedicated circuit trimmed to better match
the sensing element characteristics.
The LIS332AX has a full-scale of
capable of measuring accelerations over a
maximum bandwidth of 2.0 kHz. The device
bandwidth may be reduced by using external
capacitors. The self-test capability allows the user
to check the functioning of the system.
ST is already in the field with several hundred
million sensors which have received excellent
acceptance from the market in terms of quality,
reliability and performance.
The LIS332AX is provided in a plastic land grid
array (LGA) package.
Several years ago ST successfully pioneered the
use of this package for accelerometers. Today, ST
has the widest manufacturing capability and
strongest expertise in the world for production of
sensors in plastic LGA packages.
