LIS2L02AQ INERTIAL SENSOR: 2Axis - 2g/6g LINEAR ACCELEROMETER PRODUCT PREVIEW s s s s s s 3V TO 5.25V SINGLE SUPPLY OPERATION THE SENSITIVITY IS ADJUSTED WITH A TOTAL ACCURACY OF ±10% THE OUTPUT VOLTAGE, OFFSET, SENSITIVITY AND TEST VOLTAGE ARE RATIOMETRIC TO THE SUPPLY VOLTAGE DEVICE SENSITIVITY IS ON-CHIP FACTORY TRIMMED EMBEDDED SELF TEST HIGH SHOCK SURVIVABILITY QFN-44 ORDERING NUMBER: LIS2L02AQ DESCRIPTION The LIS2L02AQ is a dual-axis 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 to detect the acceleration, is manufactured using a dedicated process 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 trimmed to better match the sensing element characteristics. The LIS2L02AQ has a user selectable full scale of 2g, 6g and it is capable of measuring accelerations BLOCK DIAGRAM over a maximum bandwidth of 4.0 KHz for both the X and Y axis. The device bandwidth may be reduced by using external capacitances. A self-test capability allows the user to check the functioning of the system. The LIS2L02AQ is available in plastic SMD package and it is specified over a temperature range exte...
