CS4384-CQZ datasheet by Cirrus Logic

CS4384-CQZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS4384-CQZ?
  The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD), and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the performance of the CS4384-CQZ in a noisy environment?
  To optimize performance in a noisy environment, ensure proper grounding and shielding of the device, use a low-pass filter on the analog input, and consider using a separate analog ground plane. Additionally, use a high-quality clock source and ensure the clock signal is clean and stable.
• What is the maximum allowed capacitance on the analog input pins?
  The maximum allowed capacitance on the analog input pins is 10nF. Exceeding this value may affect the device's performance and stability.
• Can I use the CS4384-CQZ with a separate analog-to-digital converter (ADC)?
  Yes, the CS4384-CQZ can be used with a separate ADC. However, ensure that the ADC is compatible with the CS4384-CQZ's output format and that the interface is properly configured.
• How do I troubleshoot issues with the CS4384-CQZ's digital output?
  To troubleshoot issues with the digital output, check the clock signal, ensure proper synchronization, and verify the output format. Also, check the device's register settings and ensure that the correct output mode is selected.
