Description

The LIS302SG is a miniaturized low-power three-

axis linear accelerometer belonging to the

“piccolo” family of ST motion sensors. 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 LIS302SG has a full scale of

±2 g and it is

capable of measuring accelerations over a

maximum bandwidth of 2.0 kHz. The device

bandwidth may be reduced by using external

capacitances. The self-test capability allows the

user to check the functioning of the sensor in the

final application.

The device has three analog acceleration output

plus an embedded multiplexer that allows to

redirect the analog outputs onto a single pin for

operation with a single channel A/D converter.

The LIS302SG 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 LIS302SG belongs to a family of products

suitable for a variety of applications, including:

– Mobile terminals

– Gaming and virtual reality input devices

– Free-fall detection for data protection

– Antitheft systems and inertial navigation

– Appliance and robotics.
