LIS344ALH STMicroelectronics

LIS344ALH MEMS inertial sensor high performance 3-axis 2/6g ultracompact linear accelerometer Features 2.4 V to 3.6 V single supply operation 2 g / 6 g user selectable full-scale Low power consumption Output voltage, offset and sensitivity are ratiometric to the supply voltage LGA 16L (4x4x1.5 mm) Factory trimmed device sensitivity and offset Embedded self test RoHS/ECOPACK compliant The LIS344ALH has a dynamically user High shock survivability ( 10000 g ) selectable full-scale of 2 g / 6 g and it is capable of measuring accelerations over a Description maximum bandwidth of 1.8 kHz for all axes. The device bandwidth may be reduced by using The LIS344ALH is an ultra compact consumer external capacitances. The self-test capability low-power three-axis linear accelerometer that allows the user to check the functioning of the includes a sensing element and an IC interface system. able to take the information from the sensing element and to provide an analog signal to the The LIS344ALH is available in Land Grid Array external world. package (LGA) manufactured by ST. It is guaranteed to operate over an extended The sensing element, capable of detecting the temperature range of -40 C to +85 C. acceleration, is manufactured using a dedicated process developed by ST to produce inertial The LIS344ALH belongs to a family of products sensors and actuators in silicon. suitable for a variety of applications: The IC interface is manufactured using an ST Mobile terminals proprietary CMOS process with high level of Gaming and virtual reality input devices integration. The dedicated circuit is trimmed to Antitheft systems and inertial navigation better match the sensing element characteristics. Appliance and robotics. Table 1.
