... Functionality The LIS3L02AQ3 is a high performance, low-power, analog output 3-Axis linear accelerometer packaged in a QFN 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. ...

... Power supply decoupling capacitors (100nF ceramic or polyester + 10 as possible to the device (common design practice). The LIS3L02AQ3 allows to band limit Voutx, Vouty and Voutz through the use of external capacitors. The re- commended frequency range spans from 1.5 KHz. In particular, capacitors must be added at output pins to implement low-pass filtering for antialiasing and noise reduction ...
