LIS2L06AL Electrical Connection

Power supply decoupling capacitors (100nF ceramic or polyester + 10

µF Aluminum) should be

placed as near as possible to the device (common design practice).

The LIS2L06AL 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

the equation for the external filter cut-off frequency may be simplified as follows:

The tolerance of the internal resistor can vary typically of

110k

Ω; thus the cut-off frequency will vary accordingly. A minimum capacitance of 723 pF for
