... LIS352AR 5 Functionality The LIS352AR is a 3-axis “piccolo”, low-power, analog output linear accelerometer packaged in an LGA package. The complete device includes a sensing element and an IC interface capable of taking information from the sensing element providing an analog signal to the external world. The sensor provides three acceleration channels 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 LIS352AR allows band limiting of Voutx, Vouty and Voutz through the use of external capacitors. The recommended frequency range spans from 2.0 kHz. Capacitors must be added at the output pins to implement low-pass filtering for anti-aliasing and noise reduction, even if only the multiplexed output (Vout) is used ...

... LIS352AR The tolerance of the internal resistor can vary ±15% (typ) from its nominal value of 32 kΩ; thus the cut-off frequency will vary accordingly. A minimum capacitance of 2.5 nF for C ( required. An external capacitor can be added to the Vout pin. Values below 10 pF are recommended. Table 6. ...
