TDA4860 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the TDA4860?
  The recommended operating voltage range for the TDA4860 is 8V to 18V, with a typical voltage of 12V.
• How do I ensure stable operation of the TDA4860 in high-temperature environments?
  To ensure stable operation in high-temperature environments, it's recommended to use a heat sink with a thermal resistance of less than 10°C/W and to keep the junction temperature below 150°C.
• What is the maximum power dissipation of the TDA4860?
  The maximum power dissipation of the TDA4860 is 20W, but this can be increased to 30W with proper heat sinking.
• How do I configure the TDA4860 for a specific output voltage?
  The output voltage of the TDA4860 can be configured by adjusting the values of the feedback resistors R1 and R2, and the voltage reference pin (VREF). A higher output voltage requires a higher VREF voltage and a lower R1/R2 ratio.
• What is the purpose of the soft-start pin (SS) on the TDA4860?
  The soft-start pin (SS) on the TDA4860 is used to control the output voltage rise time during power-up. By connecting a capacitor to the SS pin, the output voltage rise time can be slowed down to prevent inrush currents and reduce electromagnetic interference (EMI).
