... LIS331AL 2.3 Absolute maximum ratings Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability ...

... When interfacing with an ADC it is important to use high input impedance input circuitries to avoid measurement errors. Note that the minimum load capacitance forms a corner frequency close to the resonance frequency of the sensor. In general the smallest possible bandwidth for a particular application should be chosen to get the best results. 10/16 LIS331AL ...

... LIS331AL 3 Functionality The LIS331AL is a nano low-power, analog output three-axis linear accelerometer packaged in a LGA package. The complete device 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. 3.1 Sensing element A proprietary process is used to create a surface micro-machined accelerometer ...

... 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 LIS331AL 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 ...
