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
LGA-14 (3x5x0.9mm)
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.
