ADXL354BEZ-RL - Analog Devices

ADXL354BEZ-RL Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A good PCB layout is crucial for optimal performance. Analog Devices recommends a 4-layer PCB with a solid ground plane, and to keep the accelerometer away from high-frequency components and traces. A dedicated analog ground plane is also recommended.
• How do I calibrate the ADXL354BEZ-RL?
  The ADXL354BEZ-RL does not require calibration in the classical sense. However, it's recommended to perform a zero-g offset calibration to account for any offset errors. This can be done by taking measurements at multiple orientations and averaging the results.
• What is the maximum acceleration range that can be measured?
  The ADXL354BEZ-RL can measure accelerations up to ±40g. However, it's recommended to operate within the specified range of ±20g for optimal performance and accuracy.
• How do I handle noise and filtering?
  Noise and filtering are critical in accelerometer applications. Analog Devices recommends using a low-pass filter with a cutoff frequency of around 100 Hz to 200 Hz to remove high-frequency noise. Additionally, using a capacitor in series with the output pins can help to reduce noise.
• What is the power consumption of the ADXL354BEZ-RL?
  The ADXL354BEZ-RL has a typical power consumption of 140 μA at 3.3 V supply voltage. However, this can vary depending on the specific application and operating conditions.
