TDA7409D Frequently Asked Questions (FAQs)

• What is the minimum operating voltage for the TDA7409D?
  The minimum operating voltage for the TDA7409D is 6.5V, but it is recommended to use 8V for optimal performance.
• Can I use the TDA7409D in a automotive application?
  Yes, the TDA7409D is qualified for automotive applications and meets the AEC-Q100 standard.
• How do I ensure the amplifier is stable?
  To ensure stability, it is recommended to use a decoupling capacitor of 100nF to 220nF between the power supply pins (VCC and GND) and to keep the layout as symmetrical as possible.
• What is the maximum power dissipation of the TDA7409D?
  The maximum power dissipation of the TDA7409D is 2.5W, but it is recommended to keep it below 2W to ensure reliable operation.
• Can I use the TDA7409D in a single-supply configuration?
  Yes, the TDA7409D can be used in a single-supply configuration, but it requires an external voltage divider to set the mid-supply voltage (VREF).
