the device (common design practice).

The LIS2L02AS4 allows to band limit Voutx, Vouty through the use of external capacitors. The recom-

mended 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 fre-

Ω, 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

Ω; thus the

case.
