LIS344ALH

MEMS inertial sensor

high performance 3-axis ±2/±6g ultracompact linear accelerometer

Features

ratiometric to the supply voltage

Description

The LIS344ALH 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 an ST

proprietary CMOS process with high level of

integration. The dedicated circuit is trimmed to

better match the sensing element characteristics.

The LIS344ALH has a dynamically user

selectable full-scale of ±2 g / ±6 g and it is

capable of measuring accelerations over a

maximum bandwidth of 1.8 kHz for all axes. The

device bandwidth may be reduced by using

external capacitances. The self-test capability

allows the user to check the functioning of the

system.

The LIS344ALH is available in Land Grid Array

package (LGA) manufactured by ST.

It is guaranteed to operate over an extended

temperature range of -40 °C to +85 °C.

The LIS344ALH 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.
