Application Notes
- Filter-Free Class-D Audio AmplifiersPDF, 259 Kb, File published: 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. - AN-1737 Managing EMI in Class D Audio Applications (Rev. A)PDF, 140 Kb, Revision: A, File published: May 1, 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 Mb, Revision: B, File published: May 1, 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. - Using Thermal Calculation Tools for Analog ComponentsPDF, 1.1 Mb, File published: Sep 2, 2010
This document provides general guidance on the use of toolsand calculations for thermal estimates of component operating temperatures for analog devices. Of particularfocus are components with direct thermal paths to the PCB which is common for components which need a low thermal resistance to manage the dissipated power. This document provides practical considerations for estimation of o - Guidelines for Measuring Audio Power Amplifier PerformancePDF, 765 Kb, File published: 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.
