... LIS344ALH 3 Functionality The LIS344ALH is an ultra compact 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. ...

... Power supply decoupling capacitors (100 nF ceramic or polyester + 10 should be placed as near as possible to the device (common design practice). The LIS344ALH allows to band limit VoutX, VoutY and VoutZ through the use of external capacitors. The recommended frequency range spans from 1.8 kHz. In particular, capacitors are added at output VoutX, VoutY, VoutZ pins to implement low-pass filtering for antialiasing and noise reduction ...
