Power supply decoupling capacitors (100nF ceramic or polyester + 10µF Aluminum) should
be placed as near as possible to the device (common design practice).
The LIS2L06AL allows to band limit Voutx and Vouty through the use of external capacitors.
The re-commended frequency range spans from DC up to 2.0kHz. In particular, capacitors
must be added at output pins to implement low-pass filtering for antialiasing and noise
reduction. The equation for the cut-off frequency (f
Taking in account that the internal filtering resistor (R
110kΩ, the equation for the external filter cut-off frequency may be simplified as follows:
The tolerance of the internal resistor can vary typically of
110kΩ; thus the cut-off frequency will vary accordingly. A minimum capacitance of 1nF for
