Design Considerations

When implementing the ADXL375BCCZ in your design:

1. Power Supply: The 2.0-3.6V operating range allows direct battery connection. Decoupling capacitors should be placed within 5mm of the VDD pin.
2. Mounting: For accurate vibration measurement, mount the sensor as close as possible to the measurement point using a rigid PCB.
3. Orientation: Remember that the sensor measures acceleration along the IC package axes - consult the datasheet for proper alignment.
4. Filtering: Use the programmable bandwidth to optimize for your specific application requirements.
