LIS2L02AL 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 LIS2L02AL 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 (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) is required in any case.
