TPA311DR Frequently Asked Questions (FAQ)

  • A good PCB layout for optimal thermal performance involves placing the TPA311DR near the edge of the board, using a large copper area for heat dissipation, and keeping the thermal vias as close to the device as possible.

  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines, and add a 10nF capacitor between the BYPASS pin and GND. Also, avoid using long traces and keep the input and output traces separate.

  • The maximum power supply voltage for the TPA311DR is 26V. Exceeding this voltage may damage the device. It's recommended to use a voltage regulator or a voltage limiter to ensure the voltage stays within the recommended range.

  • To protect the amplifier from back-EMF, use a flyback diode (e.g., 1N4007) in parallel with the inductive load. This will prevent the back-EMF from damaging the amplifier.

  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input capacitor. This value provides a good balance between noise filtering and stability.
