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.
LGA-14 (3x5x0.9mm)
The LIS302ALK has a full scale of ±2g and it 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 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.
