MAX98361AEWL+T Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the MAX98361AEWL+T. Ensure that the audio signal traces are short and away from the power supply and ground planes. Use a solid ground plane and decouple the power supply with capacitors. A 4-layer PCB with a dedicated ground plane is recommended. Refer to the application note AN-1149 for more details.
  • The gain setting depends on the input signal level and the desired output level. The MAX98361AEWL+T has a digital gain control with 32 steps. Start with a mid-range gain setting and adjust based on the signal level at the output. You can also use the AGC (Automatic Gain Control) feature to optimize the gain setting dynamically.
  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is stable before the digital circuitry is powered up. A power-up sequence of AVDD > DVDD > EN (enable) is recommended.
  • Audio noise or distortion issues can be caused by a variety of factors, including PCB layout, power supply noise, and input signal quality. Check the PCB layout for any signal integrity issues, ensure that the power supply is clean and well-regulated, and verify that the input signal is within the recommended specifications. Use an oscilloscope to measure the output signal and identify any anomalies.
  • While the MAX98361AEWL+T is optimized for a 12.288 MHz clock frequency, it can operate with other clock frequencies. However, this may affect the audio performance and clock jitter tolerance. Consult the datasheet and application notes for more information on clock frequency selection and trade-offs.
