- Guidelines for Measuring Audio Power Amplifier PerformancePDF, 765 Kb, Datei veröffentlicht: 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. - AN-1737 Managing EMI in Class D Audio Applications (Rev. A)PDF, 140 Kb, Revision: A, Datei veröffentlicht: 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.
