LIS302ALB 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 LIS302ALB allows to band limit Voutx, Vouty and Voutz through the use of external
capacitors. The recommended frequency range spans from DC up to 2.0kHz. 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 into account that the internal filtering resistor (Rout) has a nominal value equal to
32k
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
32k
Ω; thus the cut-off frequency will vary accordingly. A minimum capacitance of 2.5nF for
Cload(x, y, z) is required in any case.
An external capacitor can be added to the Vout pin. Values below 10 pF are recommended.
