LM4861MX/NOPB Frequently Asked Questions (FAQs)

  • TI recommends using a 10uF capacitor in parallel with a 0.1uF capacitor, both connected between the power supply pins (VIN and GND) and placed as close to the device as possible.
  • To ensure stability, use a minimum of 100nF capacitor between the BYPASS pin and GND, and keep the power supply traces as short as possible. Also, avoid using long wires or cables for the input signals.
  • The maximum power dissipation of the LM4861 is 2.5W. However, this value can be affected by the ambient temperature, PCB layout, and thermal management. It's essential to follow proper thermal design and heat sinking to ensure reliable operation.
  • Yes, the LM4861 can be used as a stereo amplifier by using two devices, one for each channel. However, it's essential to ensure that the power supply and ground connections are properly decoupled and isolated to prevent crosstalk and noise.
  • The minimum recommended load impedance for the LM4861 is 4 ohms, and the maximum is 32 ohms. Operating the device outside of this range may affect its performance, stability, and reliability.
