LM380N Frequently Asked Questions (FAQs)

  • The maximum power supply voltage for the LM380N is 22V. Exceeding this voltage may cause damage to the IC.
  • No, the LM380N is a mono amplifier. It is designed to amplify a single audio channel. For stereo applications, you would need two LM380N ICs, one for each channel.
  • The gain of the LM380N is determined by the ratio of the feedback resistors (R1 and R2). A higher gain can be achieved by increasing the ratio of R1 to R2. However, be careful not to exceed the maximum gain of 200, as this can lead to oscillation.
  • The LM380N can drive a minimum load impedance of 2 ohms. Driving a load impedance lower than this may cause the IC to overheat or oscillate.
  • Yes, the LM380N can drive a speaker directly, but it's recommended to use a capacitor in series with the speaker to block DC voltage and prevent damage to the speaker.
