LIS331AL MEMS inertial sensor: 3-axis - 2g analog output nano accelerometer Features Single voltage supply operation 2.0g full-scale Output voltage, offset and sensitivity are ratiometric to the supply voltage LGA 16 (3x3x1.0mm) Factory trimmed device sensitivity and offset Embedded self test process developed by ST to produce inertial ECOPACK lead-free compliant sensors and actuators in silicon. High shock survivability (10000g) The IC interface is manufactured using a CMOS process that allows high level of integration to Applications Mobile terminals design a dedicated circuit which is trimmed to Gaming and virtual reality input devices better match the sensing element characteristics. Antitheft systems and Inertial Navigation The LIS331AL is capable of measuring Appliance and robotics accelerations over a maximum bandwidth of 2.0kHz. The device bandwidth may be reduced by Description using external capacitances. A self-test capability allows the user to check the functioning of the The LIS331AL is the smallest consumer low- system. power three-axis linear accelerometer that The LIS331AL is available in Land Grid Array includes a sensing element and an IC interface package (LGA) and it is guaranteed to operate able to take the information from the sensing over an extended temperature range of -40C to element and to provide an analog signal to the +85C. external world. The sensing element, capable of detecting the acceleration, is manufactured using a dedicated Table 1.
