LIS332AR electrical connection
Power supply decoupling capacitors (100 nF ceramic or polyester + 10 F aluminum) should
be placed as near as possible to the device (common design practice).
The LIS332AR allows band limiting of Voutx, Vouty and Voutz through the use of external
capacitors. The recommended frequency range spans from DC up to 2.0 kHz. Capacitors
must be added at the output pins to implement low-pass filtering for anti-aliasing 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 of 32 k, the
equation for the external filter cut-off frequency may be simplified as follows:
The tolerance of the internal resistor can vary ±15% (typ) from its nominal value of 32 k
;
thus the cut-off frequency will vary accordingly. A minimum capacitance of 2.5 nF for CLOAD
(x, y, z) is required.
