... LIS344AL This is a Mechanical Shock sensitive device, improper handling can cause permanent damages to the part This is an ESD sensitive device, improper handling can cause permanent damages to the part 2.4 Terminology Sensitivity describes the gain of the sensor and can be determined by applying 1g acceleration to it. As the sensor can measure DC accelerations this can be done easily by pointing the axis of interest towards the center of the Earth, note the output value, rotate the sensor by 180 degrees (point to the sky) and note the output value again thus applying ± ...

... Power supply decoupling capacitors (100 nF ceramic or polyester + 10 µF Aluminum) should be placed as near as possible to the device (common design practice). The LIS344AL allows to band limit VoutX, VoutY and VoutZ through the use of external capacitors. The recommended frequency range spans from 2.0 kHz. In particular, capacitors are added at output VoutX, VoutY, VoutZ pins to implement low-pass filtering for antialiasing and noise reduction ...
