TDA7266M datasheet by STMicroelectronics

TDA7266M Frequently Asked Questions (FAQs)

• What is the recommended power supply decoupling for the TDA7266M?
  A 10uF capacitor in parallel with a 100nF capacitor is recommended for power supply decoupling to ensure stable operation.
• How do I ensure the TDA7266M is protected from overheating?
  Ensure good heat dissipation by providing a heat sink or a metal pad on the PCB, and consider using a thermal shutdown circuit to prevent overheating.
• What is the maximum power that can be delivered to the speaker?
  The maximum power that can be delivered to the speaker depends on the supply voltage and the speaker impedance. For a 12V supply, the maximum power is around 20W into a 4Ω load.
• How do I configure the gain of the TDA7266M?
  The gain of the TDA7266M can be configured by selecting the appropriate resistors for the feedback network. A gain of 20dB is typical, but can be adjusted to suit the application.
• Is the TDA7266M suitable for use in automotive applications?
  Yes, the TDA7266M is AEC-Q100 qualified, making it suitable for use in automotive applications. However, ensure that the device is properly protected from voltage transients and other automotive-specific requirements.
