Q & A

  1. What is the maximum output power of the TDA8922CJ/N1,112 in mono configuration?
    The maximum output power in mono configuration is 155W at 8Ohm load.
  2. What are the supply voltage ranges for the TDA8922CJ/N1,112?
    The supply voltage range is from ±12.5V to ±32.5V.
  3. What types of protection mechanisms are built into the TDA8922CJ/N1,112?
    The device includes overvoltage, overtemperature, and overcurrent protection mechanisms.
  4. Can the TDA8922CJ/N1,112 be configured in different operating modes?
    Yes, it can be configured in standby, mute, and full operational modes.
  5. What is the thermal foldback feature in the TDA8922CJ/N1,112?
    The thermal foldback feature gradually reduces the output power if the junction temperature exceeds a certain threshold to stabilize the temperature.
  6. What is the package type of the TDA8922CJ/N1,112?
    The package type is 24-HSOP (0.433", 11.00mm Width) Exposed Pad.
  7. Is the TDA8922CJ/N1,112 suitable for stereo and mono configurations?
    Yes, it can be configured in both stereo single-ended and mono bridge-tied load configurations.
  8. What is the operating temperature range of the TDA8922CJ/N1,112?
    The operating temperature range is from -40°C to 85°C (TA).
  9. Does the TDA8922CJ/N1,112 have differential inputs?
    Yes, it features differential inputs for high signal integrity.
  10. How does the overtemperature protection work in the TDA8922CJ/N1,112?
    If the temperature continues to rise despite thermal foldback, the overtemperature protection will shut down the device until the temperature drops below the protection threshold.
