TDA7267A Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be used with the TDA7267A?
  The maximum power supply voltage for the TDA7267A is 18V. Exceeding this voltage may damage the device.
• How do I ensure the TDA7267A operates within its safe operating area (SOA)?
  To ensure the TDA7267A operates within its SOA, ensure the output current does not exceed 3.5A, and the junction temperature does not exceed 150°C. Also, avoid operating the device at high power supply voltages and high output currents simultaneously.
• What is the recommended heatsink for the TDA7267A?
  The recommended heatsink for the TDA7267A is a thermal resistance of 10°C/W or lower. A heatsink with a thermal resistance of 5°C/W or lower is recommended for high-power applications.
• How do I protect the TDA7267A from back-EMF when using inductive loads?
  To protect the TDA7267A from back-EMF, use a freewheeling diode (e.g., 1N4007) in parallel with the inductive load. This diode will absorb the back-EMF and prevent it from damaging the IC.
• What is the minimum and maximum gain that can be set using the gain pins (G1 and G2)?
  The minimum gain that can be set using the gain pins is 20dB, and the maximum gain is 30dB.
