LIS352AX electrical connection

Power supply decoupling capacitors (100 nF ceramic or polyester + 10 µF aluminum) should

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

The LIS352AX 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, even if only the multiplexed output (Vout) is used. 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 kΩ, the

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