描述 Description

The LIS3LV02DL 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 LIS3LV02DL 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 LIS3LV02DL is available in plastic SMD

package and it is specified over a temperature

range extending from -40°C to +85°C.

The LIS3LV02DL 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
