the device (common design practice).
The LIS3L02AS4 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 ( ) of the external filters is:
Taking in account that the internal filtering resistor (R
tion 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 110kΩ; thus the
cut-off frequency will vary accordingly. A minimum capacitance of 320 pF for C
