LM4890MMX/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends using a 10uF capacitor in parallel with a 0.1uF capacitor between the power supply pins (VCC and GND) to ensure stable operation.
  • Ensure good airflow around the device, use a heat sink if necessary, and avoid operating the device at maximum power for extended periods. Also, follow the recommended PCB layout and thermal management guidelines.
  • The maximum allowed output power is 2.5W per channel into a 4Ω load, but this can be limited by the power supply voltage, output impedance, and thermal considerations.
  • No, the LM4890MMX/NOPB is not designed for bridged operation. It is intended for stereo or mono applications only.
  • Use a shielded enclosure, keep the device away from antennas and other EMI sources, and follow good PCB layout practices such as separating analog and digital grounds and using EMI filters.
