Application Notes

  • Power Supply Recommendations for DVD Receivers
    PDF, 153 Kb, File published: May 4, 2005
    Selecting the optimal power supply for a non feed back digital amplifier can bechallenging. Music is dynamic, so the power consumption is changing dramatically,from almost zero to maximum within a few ms.Designing the power supply so powerful that it can deliver the total amplifier outputpower continuously is too costly and usually unnecessary.Designing the power supply too small gives p
  • Power Rating in Audio Amplifier (Rev. A)
    PDF, 514 Kb, Revision: A, File published: Mar 4, 2005
    Average consumers often weigh heavily on cost versus power rating of audio amplifiers as their basis for purchasing one. Depending on the marketing strategy, the powerrating methodology for audio amplifiers can vary from manufacturer to manufacturer.The purpose of this document is to clarify three commonly used power ratings: average power, peak power, and PMPO.The following Texas Instru
