... LIS332AR LIS332ARTR February 2010 circuit which is trimmed to better match the sensing element characteristics. The LIS332AR has a full-scale of ±2 g, and is capable of measuring accelerations over a maximum bandwidth of 2.0 kHz. The device bandwidth may be reduced by using external capacitors. The self-test capability allows the user to check the functioning of the sensor in the final application ...

... 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 LIS332AR allows band limiting of Voutx, Vouty and Voutz through the use of external capacitors. The recommended frequency range spans from 2.0 kHz. Capacitors must be added at the output pins to implement low-pass filtering for anti-aliasing and noise reduction ...
