LIS302ALK

MEMS motion sensor

3-axis - ±2g analog output "piccolo" accelerometer

Features

(see Section 5)

Description

The LIS302ALK is a miniaturized low-power

three-axis linear accelerometer. It 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 motion

sensors and actuators in silicon.

The IC interface is manufactured using a CMOS

process that allows to design a dedicated circuit

which is trimmed to better match the sensing

element characteristics. The device can be

operated from 2.16V to 3.6V.

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 sensor in the final application

without thew need to move or tilt the sensor.

The LIS302ALK is available in plastic Thin Land

Grid Array package (TLGA) and it is guaranteed

to operate over an extended temperature range

from -40°C to +85°C.

The LIS302ALK belongs to a family of products

suitable for a variety of applications:

– Mobile terminals

– Gaming and Virtual Reality input devices

– Free-fall detection for data protection

– Antitheft systems and Inertial Navigation

– Appliance and Robotics.
