MAX9728AEUD+T Frequently Asked Questions (FAQs)

  • A good PCB layout for the MAX9728AEUD+T involves separating the analog and digital grounds, using a solid ground plane, and placing the device close to the audio input and output connectors. Additionally, it's recommended to use a ferrite bead or a 10Ω resistor in series with the VDD pin to filter out high-frequency noise.
  • The gain setting for the MAX9728AEUD+T depends on the specific audio application and the desired output level. A good starting point is to set the gain to 0dB (default) and then adjust it based on the output level required. The gain can be adjusted using the GAIN pin, which has a range of -12dB to +12dB in 1dB steps.
  • The maximum input voltage that the MAX9728AEUD+T can handle is 3.5Vrms, which is equivalent to 5Vpeak. Exceeding this voltage may result in distortion or damage to the device.
  • To properly power down the MAX9728AEUD+T, the SHDN pin should be pulled low (less than 0.4V) to put the device in shutdown mode. This reduces the quiescent current to less than 1μA, minimizing power consumption when the device is not in use.
  • The recommended capacitor value for the VDD pin decoupling is 1μF to 10μF, with a voltage rating of at least 6.3V. A ceramic capacitor with an X7R or X5R dielectric is recommended for its low ESR and high reliability.
