1 / 13 page  1/13 LIS3L02AQ3 May 2005 1 Features ■ 2.4V TO 3.6V SINGLE SUPPLY OPERATION ■ LOW POWER CONSUMPTION ■ ±2g/±6g USER SELECTABLE FULL-SCALE ■ BETTER THAN 0.5mg RESOLUTION OVER 100Hz BANDWIDTH ■ EMBEDDED SELF TEST AND POWER DOWN ■ OUTPUT VOLTAGE, OFFSET AND SENSITIVITY RATIOMETRIC TO THE SUPPLY VOLTAGE ■ HIGH SHOCK SURVIVABILITY ■ ECO-PACK COMPLIANT 2 Description The LIS3L02AQ3 is a low-power 3-Axis linear capac- itive 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 accel- eration, is manufactured using a dedicated process developed by ST to produce inertial sensors and ac- tuators in silicon. The IC interface is manufactured using a standard CMOS process that allows high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The LIS3L02AQ3 has a user selectable full scale of ±2g, ±6g and it is capable of measuring accelerations over a bandwidth of 1.5 KHz for all axes. The device bandwidth may be reduced by using external capac- itances. A self-test capability allows to check the me- chanical and electrical signal path of the sensor. The LIS3L02AQ3 is available in plastic SMD pack- age and it is specified over an extended temperature range of -40°C to +85°C. The LIS3L02AQ3 belongs to a family of products suitable for a variety of applications: – Mobile terminals – Gaming and Virtual Reality input devices – Free-fall detection for data protection – Antitheft systems and Inertial Navigation – Appliance and Robotics MEMS INERTIAL SENSOR: 3-Axis - ±2g/±6g LINEAR ACCELEROMETER Figure 2.
