  • Short-to-Battery Protection Strategies for Class-D Amplifiers
    PDF, 3.2 Mb, Archivo publicado: nov 11, 2016
    This document introduces the potential faults that can occur in class-D amplifier solutions, and describes how most faults are intrinsically protected for and how to extend coverage to protect against all short-circuit faults. Of particular focus is the case when an output is shorted to a battery voltage higher than the device supply voltage. This fault allows the parasitic body diode found in the
  • Filter-Free Class-D Audio Amplifiers
    PDF, 259 Kb, Archivo publicado: nov 9, 2009
    Traditional Class-D amplifiers lose efficiency if they do not use output LC filters. Texas Instruments offers many Class-D amplifiers that are designated Filter-Free. This means they do not require an output LC filter to maintain high efficiency. However, in some cases an LC or ferrite bead filter is required for EMC.
  • Power Rating in Audio Amplifier (Rev. A)
    PDF, 514 Kb, Revisión: A, Archivo publicado: marzo 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

  • Guidelines for Measuring Audio Power Amplifier Performance
    PDF, 765 Kb, Archivo publicado: oct 30, 2001
    This application note provides guidelines for measuring the date sheet parameters of Texas Instruments audio power amplifiers (APAs) using prefabricated evaluation modules (EVMs). The primary equipment used for the measurements consists of the System Two audio measurement system by Audio Precision , a digital multimeter (DMM), and a dc power supply.
