LM384N/NOPB Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM384N?
  The maximum power dissipation of the LM384N is 1.4W, but it can be increased to 2.5W with proper heat sinking.
• Can I use the LM384N as a voltage regulator?
  Yes, the LM384N can be used as a voltage regulator, but it's primarily designed as an audio power amplifier. For voltage regulation, consider using a dedicated voltage regulator IC like the 78L05 or 79L05.
• How do I choose the correct gain resistors for the LM384N?
  The gain resistors (R1 and R2) should be chosen based on the desired gain and input impedance. A good starting point is to use R1 = 1kΩ and R2 = 2kΩ for a gain of 2. Adjust these values as needed to achieve the desired gain and input impedance.
• What is the minimum and maximum supply voltage for the LM384N?
  The minimum supply voltage for the LM384N is 6V, and the maximum supply voltage is 22V. Operating the device outside of this range may affect its performance and reliability.
• Can I use the LM384N in a bridged amplifier configuration?
  Yes, the LM384N can be used in a bridged amplifier configuration to increase the power output. However, this requires careful design and layout to ensure proper operation and to prevent oscillations.
