Description
The LIS3LV02DQ is a three axes digital output
linear accelerometer that includes a sensing
element and an IC interface able to take the
information from the sensing element and to
provide the measured acceleration signals to the
external world through an I2C/SPI serial interface.
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 instead is manufactured using a
CMOS process that allows high level of integration
to design a dedicated circuit which is factory
trimmed to better match the sensing element
characteristics.
The LIS3LV02DQ has a user selectable full scale
of
±2g, ±6g and it is capable of measuring
acceleration over a bandwidth of 640 Hz for all
axes. The device bandwidth may be selected
accordingly to the application requirements. A
self-test capability allows the user to check the
functioning of the system
The device may be configured to generate an
inertial wake-up/free-fall interrupt signal when a
programmable acceleration threshold is crossed
at least in one of the three axes.
The LIS3LV02DQ is available in plastic SMD
package and it is specified over a temperature
range extending from -40°C to +85°C.
The LIS3LV02DQ belongs to a family of products
suitable for a variety of applications:
Free-Fall detection
Motion activated functions in portable terminals
Antitheft systems and Inertial navigation
Gaming and Virtual Reality input devices
Vibration Monitoring and Compensation
