LM4871LD/NOPB Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply the power supply voltage (VCC) before applying the input signal. This ensures that the internal biasing and filtering circuits are properly initialized.
  • The gain setting can be optimized by adjusting the values of the external resistors (Rf and Rg) connected to the gain pins (GAIN1 and GAIN2). The optimal values can be determined through experimentation or by using TI's audio amplifier design tool.
  • The maximum power handling capability of the LM4871 is 2.5W per channel into a 4Ω load. However, this can be increased to 5W per channel by using an external heat sink and ensuring proper thermal management.
  • To reduce noise and hiss, ensure that the power supply is well-regulated and decoupled, use a low-noise voltage regulator, and add bypass capacitors to the power supply lines. Additionally, use a high-quality audio capacitor and ensure that the PCB layout is optimized for low noise.
  • Yes, the LM4871 can be used in a bridged configuration to increase the power output. However, this requires careful consideration of the power supply, heat sinking, and PCB layout to ensure reliable operation.
