... 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. 8/17 LIS302ALB ...

... LIS302ALB 3 Functionality The LIS302ALB is an “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 (100nF ceramic or polyester + 10μF Aluminum) should be placed as near as possible to the device (common design practice). The LIS302ALB allows to band limit Voutx, Vouty and Voutz through the use of external capacitors. The recommended frequency range spans from 2.0kHz. Capacitors must be added at output pins to implement low-pass filtering for antialiasing and noise reduction ...
