Power supply decoupling capacitors (100nF ceramic or polyester + 10µF Aluminum) should
be placed as near as possible to the device (common design practice).
The LIS244AL allows to band limit Voutx, Vouty through the use of external capacitors. The
recommended frequency range spans from DC up to 2.0kHz. In particular, capacitors are
added at output Voutx, Vouty pins to implement low-pass filtering for antialiasing and noise
reduction. The equation for the cut-off frequency (f
Equation 1
Taking into account that the internal filtering resistor (R
32kΩ , the equation for the external filter cut-off frequency may be simplified as follows:
