- Short-to-Battery Protection Strategies for Class-D AmplifiersPDF, 3.2 Мб, Файл опубликован: 11 ноя 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 AmplifiersPDF, 259 Кб, Файл опубликован: 9 ноя 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 Кб, Версия: A, Файл опубликован: 4 мар 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 - AN-1737 Managing EMI in Class D Audio Applications (Rev. A)PDF, 140 Кб, Версия: A, Файл опубликован: 1 май 2013
Electromagnetic interference (EMI) is an unwanted disturbance caused in an electrical circuit byelectromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, orotherwise degrade the effective performance of the circuit. - AN-1849 An Audio Amplifier Power Supply Design (Rev. B)PDF, 1.9 Мб, Версия: B, Файл опубликован: 1 май 2013
This application report provides design information for a power supply for use with our newest offering of high-performance, ultra high-fidelity audio amplifier input stage ICs. - Guidelines for Measuring Audio Power Amplifier PerformancePDF, 765 Кб, Файл опубликован: 30 окт 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.
