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, 修订版: A, 档案已发布: 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, 修订版: B, 档案已发布: 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. - AN-1497 Filterless Class D Amplifiers (Rev. A)PDF, 190 Kb, 修订版: A, 档案已发布: May 1, 2013
As portable electronic devices continue to shrink in size, manufacturers look for ways to push theenvelope and develop the smallest, yet most functional product available. The promise of longer batterylife, smaller size and an enhanced sensory experience appeals to customers. Like the voltage regulatormarket, where system designers moved away from the simple but power hungry linear regulator
