LM4871M/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 circuitry is established before the input signal is applied.
  • The gain of the LM4871M can be optimized by adjusting the values of the external resistors (Rf and Rg) and capacitors (Ci and Co). The optimal values will depend on the specific application and the desired frequency response.
  • The maximum power dissipation of the LM4871M is 1.4W. This should be taken into account when designing the thermal management of the system.
  • Yes, the LM4871M can be used in a stereo audio application. The device has a stereo audio output and can drive stereo headphones or speakers.
  • To reduce noise and distortion, ensure that the power supply is well-regulated and decoupled, use high-quality components, and minimize the length of the signal paths. Additionally, consider using a low-pass filter to remove high-frequency noise.
