1 / 14 page 1/14 LIS2L02AS4 December 2005 1 Features ■ 2.4V TO 5.25V SINGLE SUPPLY OPERATION ■ LOW POWER CONSUMPTION ■ ±2g/±6g USER SELECTABLE FULL-SCALE ■ 0.3mg RESOLUTION OVER 100Hz BANDWIDTH ■ EMBEDDED SELF TEST AND POWER DOWN ■ OUTPUT VOLTAGE, OFFSET AND SENSITIVITY RATIOMETRIC TO THE SUPPLY VOLTAGE ■ HIGH SHOCK SURVIVABILITY ■ LEAD FREE AND ECOPACK COMPATIBLE 2 Description The LIS2L02AS4 is a low-power two axes 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 ac- celeration, is manufactured using a dedicated pro- cess developed by ST to produce inertial sensors and actuators 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 LIS2L02AS4 has a user selectable full scale of ±2g, ±6g and it is capable of measuring acceler- ations over a bandwidth of 1.5kHz for all axes. The device bandwidth may be reduced by using exter- nal capacitances. A self-test capability allows to check the mechanical and electrical signal path of the sensor. The LIS2L02AS4 is available in plastic SMD pack- age and it is specified over an extended tempera- ture range of -40°C to +85°C. The LIS2L02AS4 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: 2-Axis - ±2g/±6g LINEAR ACCELEROMETER Figure 2.
