- Layout Guidelines For TPA300x Series PartsPDF, 647 Kb, Archivo publicado: jul 15, 2003
This article provides a well-reinforced procedure for the PCB layout task as it pertains to the TPA300x series of class D amplifiers. This information can also be used in the layout of the TPA200x series, or any other class D audio amplifier.This task needs a logical sequence. If we simply jump into the layout task, without understanding how the circuits work, we risk not having an optimal end - AN-1737 Managing EMI in Class D Audio Applications (Rev. A)PDF, 140 Kb, Revisión: A, Archivo publicado: mayo 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, Revisión: B, Archivo publicado: mayo 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, 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.
