PAM8403DR datasheet by Diodes Incorporated

PAM8403DR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A good PCB layout for the PAM8403DR involves keeping the audio signal traces short and away from the power supply traces, using a solid ground plane, and placing the decoupling capacitors close to the IC.
• How do I optimize the gain setting for my specific application?
  The gain setting of the PAM8403DR can be optimized by adjusting the values of the external resistors Rf and Ri. A higher gain setting can be achieved by increasing the value of Rf or decreasing the value of Ri.
• What is the maximum power dissipation of the PAM8403DR?
  The maximum power dissipation of the PAM8403DR is dependent on the ambient temperature and the thermal resistance of the PCB. According to the datasheet, the maximum power dissipation is 2.5W at an ambient temperature of 25°C.
• Can I use the PAM8403DR with a single power supply?
  Yes, the PAM8403DR can be used with a single power supply. The IC has a built-in voltage regulator that allows it to operate from a single power supply voltage.
• How do I filter out noise and EMI in my audio circuit?
  To filter out noise and EMI in your audio circuit, you can add external filters such as RC filters or ferrite beads to the audio signal lines. Additionally, using a shielded cable and keeping the audio circuit away from noisy components can help reduce noise and EMI.
