LIS244AL

MEMS motion sensor:

2-axis - ±2g ultracompact linear accelerometer

Features

■

ratiometric to the supply voltage

Description

The LIS244AL is an ultra compact consumer low-

power two-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 LIS244AL 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 LIS244AL 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 LIS244AL 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.

Note:

Tape & Reel parts are compliant to International Standard EIA-481.
