... 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. 10/19 Table 3, then the sensor is working properly and the parameters LIS302SG ...

... LIS302SG 3 Functionality The LIS302SG is a “piccolo” 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. The sensor provides the three accelerations and one multiplexed analog output ...

... 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 LIS302SG allows to band limit Voutx, Vouty and Voutz through the use of external capacitors. The recommended frequency range spans from 2.0 kHz. Capacitors must be added at output pins to implement low-pass filtering for antialiasing and noise reduction, even if the only multiplexed output (Vout) is used ...
