ADXL354BEZ - Analog Devices

ADXL354BEZ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the ADXL354BEZ?
  A good PCB layout for the ADXL354BEZ involves keeping the accelerometer away from high-current carrying traces, using a solid ground plane, and minimizing the length of the traces connected to the accelerometer's pins. A 4-layer PCB with a dedicated analog ground plane is recommended.
• How do I calibrate the ADXL354BEZ?
  The ADXL354BEZ does not require calibration in the classical sense. However, it's recommended to perform a zero-g offset calibration by taking the average of multiple readings at zero-g acceleration to determine the offset. This can be done during the manufacturing process or during system startup.
• What is the maximum acceleration range that the ADXL354BEZ can measure?
  The ADXL354BEZ can measure accelerations up to ±250g, but it's recommended to limit the acceleration to ±200g to ensure accurate measurements and prevent damage to the device.
• Can I use the ADXL354BEZ in high-temperature applications?
  The ADXL354BEZ is rated for operation up to 125°C, but its accuracy and sensitivity may degrade at high temperatures. It's recommended to use the device within its specified operating temperature range of -40°C to 125°C for optimal performance.
• How do I filter out noise and vibrations when using the ADXL354BEZ?
  The ADXL354BEZ has a built-in 50 Hz low-pass filter, but additional filtering may be necessary depending on the application. Digital filtering techniques such as moving averages or low-pass filters can be used to reduce noise and vibrations.
