TDA7294HS Frequently Asked Questions (FAQs)

  • The maximum power supply voltage for the TDA7294HS is 40V, but it's recommended to operate it between 12V to 36V for optimal performance.
  • To prevent overheating, ensure good heat sinking, use a heat sink with a thermal resistance of 2°C/W or less, and keep the ambient temperature below 40°C. Also, avoid high power dissipation and use a thermal shutdown circuit if possible.
  • The TDA7294HS can drive loads with impedance between 2Ω and 8Ω. However, for optimal performance, it's recommended to use a load impedance of 4Ω or higher.
  • The gain of the TDA7294HS can be configured by connecting a resistor (Rg) between the gain pin (pin 3) and ground. The gain is calculated as 20 dB + 20log(Rg/1kΩ).
  • The bootstrap capacitor (Cb) is used to decouple the high-voltage power supply from the low-voltage control circuitry. It helps to reduce power supply noise and improve the amplifier's overall performance.
