TDA7498 Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends using a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, both connected as close as possible to the power supply pins (VP and VN) to ensure stable operation.
  • The gain of the TDA7498 can be configured by connecting a resistor (Rg) between the GAIN pin and the negative power supply (VN). The gain is calculated as 20 dB + (Rg/1.2 kΩ).
  • The maximum power dissipation of the TDA7498 is 30W, assuming a junction temperature of 150°C and a thermal resistance of 2.5°C/W. However, this value can be derated based on the ambient temperature and the thermal design of the system.
  • Yes, the TDA7498 can be used in a bridged configuration to increase the output power. In this configuration, two amplifiers are connected in anti-phase to drive a single load, effectively doubling the output power.
  • The TDA7498 has a built-in thermal shutdown protection that turns off the amplifier if the junction temperature exceeds 150°C. Additionally, a heatsink can be used to dissipate heat and reduce the risk of overheating.
