LM386M-1/NOPB Frequently Asked Questions (FAQs)

  • The maximum power supply voltage for the LM386M-1/NOPB is 15V. Exceeding this voltage may damage the device.
  • The gain of the LM386M-1/NOPB can be set using an external resistor and capacitor network. A gain of 20 is the default, but it can be increased to 50 or 200 by adding external components. Choose a gain that meets your application's requirements.
  • The minimum voltage required for the LM386M-1/NOPB to operate is 4V. However, the device may not function optimally at this voltage, and a minimum of 6V is recommended for most applications.
  • While the LM386M-1/NOPB can be used as a line driver, it's not the most suitable device for this application. The device is primarily designed as an audio power amplifier, and its output impedance is not optimized for driving long cables.
  • To reduce noise and hum, ensure that the power supply is well-regulated and decoupled, use a low-ESR capacitor for the power supply bypass, and keep the input and output traces as short as possible. Additionally, consider adding a noise filter or a ferrite bead to the power supply lines.
