LM380N-8/NOPB datasheet by Texas Instruments

LM380N-8/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A good PCB layout for the LM380N-8/NOPB involves keeping the input and output traces short and away from each other, using a ground plane, and placing decoupling capacitors close to the IC.
• How do I choose the right gain resistors for my application?
  The gain resistors (R1 and R2) should be chosen based on the desired gain and input impedance. A higher gain requires smaller resistors, while a lower gain requires larger resistors. Typically, R1 is 1 kΩ to 10 kΩ and R2 is 2 kΩ to 20 kΩ.
• What is the maximum power dissipation of the LM380N-8/NOPB?
  The maximum power dissipation of the LM380N-8/NOPB is 15W, but this can be increased by using a heat sink or reducing the ambient temperature.
• Can I use the LM380N-8/NOPB in a bridged configuration?
  Yes, the LM380N-8/NOPB can be used in a bridged configuration to increase the power output. However, this requires additional components and careful PCB layout to ensure proper operation.
• How do I protect the LM380N-8/NOPB from overheating?
  To protect the LM380N-8/NOPB from overheating, ensure good airflow, use a heat sink if necessary, and monitor the junction temperature (TJ) to prevent it from exceeding 150°C.
