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.
