LM4667MM/NOPB datasheet by Texas Instruments

LM4667MM/NOPB Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be used with the LM4667MM/NOPB?
  The maximum power supply voltage is 15V, but it's recommended to operate within 12V to ensure reliable operation and minimize heat generation.
• How do I ensure the amplifier doesn't oscillate or produce unwanted noise?
  To prevent oscillation and noise, ensure proper PCB layout, use a low-ESR capacitor for power supply decoupling, and add a 10nF capacitor between the BYPASS pin and ground.
• What is the recommended output impedance for the LM4667MM/NOPB?
  The recommended output impedance is 4 ohms or higher to ensure stable operation and minimize distortion.
• Can I use the LM4667MM/NOPB in a bridged configuration?
  Yes, the LM4667MM/NOPB can be used in a bridged configuration to increase power output, but ensure proper PCB layout and heat sinking to prevent overheating.
• How do I protect the amplifier from overheating?
  Use a heat sink with a thermal resistance of 10°C/W or lower, ensure good airflow, and consider adding thermal monitoring and shutdown circuitry to prevent damage.
