Application Notes
- Short-to-Battery Protection Strategies for Class-D AmplifiersPDF, 3.2 Mb, File published: 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 - Maximun Slew Rate on High-Voltage Pins for TPA3111D1PDF, 52 Kb, File published: Feb 1, 2012
This document provides important information on the maximum slew rate on certain high-voltage pins of the TPS3111D1. - Class-D Amplifier External Load DiagnosticsPDF, 155 Kb, File published: Jan 23, 2017
This application report provides design information for an external load diagnostics circuit to detect andidentify electrical faults between the output of an audio amplifier and a target speaker. While theTPA3111D1-Q1 class-D amplifier is used as an example in this application note, this design methodologyis relevant for most class-D amplifiers to provide external fault diagnostics. - 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. - 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 - 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. - 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.
