LIS3L02AL electrical connection
Power supply decoupling capacitors (100nF ceramic or polyester + 10
F Aluminum) should
be placed as near as possible to the device (common design practice).
The LIS3L02AL allows to band limit Voutx, Vouty and Voutz through the use of external
capacitors. The re-commended frequency range spans from DC up to 1.5 KHz. 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 (ft) of the external filters is:
Taking in account that the internal filtering resistor (Rout) has a nominal value equal to
110k
, the equation for the external filter cut-off frequency may be simplified as follows:
The tolerance of the internal resistor can vary typically of ±20% within its nominal value of
110k
; thus the cut-off frequency will vary accordingly. A minimum capacitance of 1nF for
Cload(x, y, z) is required in any case.
