LM3881MMX/NOPB Frequently Asked Questions (FAQs)

  • TI recommends using a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, placed as close as possible to the power pins (VIN and GND) to ensure stable operation.
  • The gain of the LM3881 can be optimized by adjusting the values of the feedback resistors (Rf and Ri) and the input capacitor (Ci). A higher gain can be achieved by increasing the ratio of Rf to Ri, while a lower gain can be achieved by decreasing the ratio.
  • The maximum power dissipation of the LM3881 is 20W, assuming a junction temperature of 150°C. However, this value can be derated based on the ambient temperature and the thermal resistance of the package.
  • Yes, the LM3881 can be used as a headphone amplifier, but it's essential to ensure that the output power is limited to avoid damaging the headphones or the amplifier. A maximum output power of 1W per channel is recommended for headphone applications.
  • To protect the LM3881 from overvoltage and undervoltage conditions, TI recommends using a voltage regulator or a voltage supervisor to ensure that the input voltage remains within the recommended operating range of 9V to 12V.
