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.

g, and is

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.
