Description
The LIS344ALH is an ultra compact consumer
low-power three-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 an ST
proprietary CMOS process with high level of
integration. The dedicated circuit is trimmed to
better match the sensing element characteristics.
LGA 16 (4x4x1.5 mm)
The LIS344ALH has a dynamically user
selectable full-scale of ±2 g / ±6 g and it is
capable of measuring accelerations over a
maximum bandwidth of 1.8 kHz for all axes. The
device bandwidth may be reduced by using
external capacitances. The self-test capability
allows the user to check the functioning of the
system.
The LIS344ALH is available in Land Grid Array
package (LGA) manufactured by ST.
It is guaranteed to operate over an extended
temperature range of -40 °C to +85 °C.
The LIS344ALH 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.
