TDA7297 datasheet by STMicroelectronics

TDA7297 Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be used with the TDA7297?
  The maximum power supply voltage for the TDA7297 is 40V, but it's recommended to operate it between 12V to 36V for optimal performance.
• How do I protect the TDA7297 from overheating?
  To prevent overheating, ensure good heat sinking, use a heat sink with a thermal resistance of less than 10°C/W, and keep the ambient temperature below 40°C.
• What is the minimum load impedance required for the TDA7297?
  The minimum load impedance for the TDA7297 is 2 ohms, but it's recommended to use a load impedance of 4 ohms or higher for optimal performance.
• Can I use the TDA7297 as a bridge amplifier?
  Yes, the TDA7297 can be used as a bridge amplifier, but it requires an external circuit to invert the input signal to one of the amplifier channels.
• How do I mute the TDA7297?
  The TDA7297 has a built-in mute function that can be controlled by applying a logic low signal to the MUTE pin. This will reduce the output voltage to near zero.
