Description

The LIS3L02DQ is a tri-axis 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 mea- sured acceleration signals to the external world through an I 2C/SPI serial interface.

The sensing element, capable to detect the accel- eration, is manufactured using a dedicated pro- cess called THELMA (Thick Epi-Poly Layer for Microactuators and Accelerometers) 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 char- acteristics.

The LIS3L02DQ is capable of measuring acceler- ations over a maximum bandwidth of 2.0 KHz for the X, Y axis and Z axis. The device bandwidth may be selected accordingly to the application re- quirements. A self-test capability allows the user to check the functioning of the system.

The device may be configured to generate an iner- tial wake-up/interrupt signal when a programma- ble acceleration threshold is exceeded along one of the three axis.

The LIS3L02DQ is available in plastic SMD pack- age and it is specified over a temperature range extending from -20°C to +70°C. The LIS3L02DQ belongs to a family of products suitable for a variety of applications:
    Motion activated functions in mobile terminals
    Antitheft systems and Inertial navigation
    Gaming and Virtual Reality input devices
    Vibration Monitoring and Compensation
