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 LIS352AX allows band limiting of Voutx, Vouty and Voutz through the use of external
capacitors. The recommended frequency range spans from DC up to 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. The equation for the cut-off
frequency ( f
Taking into account that the internal filtering resistor (R
equation for the external filter cut-off frequency may be simplified as follows:
