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:

, the equa-

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 110k

Ω; thus the

any case.
