应用须知
- Guidelines for Measuring Audio Power Amplifier PerformancePDF, 765 Kb, 档案已发布: 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. - Calculating Gain for Audio Amplifiers (Rev. A)PDF, 238 Kb, 修订版: A, 档案已发布: Sep 1, 2005
This application report explains the different types of audio power amplifier configurations, such as the single-ended (SE), the bridge-tied load (BTL), and the fully differential audio amplifier. Each configuration is illustrated with a block diagram, gain equations, and an example using realistic scenarios to illustrate to engineers how to calculate the gain of their audio amplifier. - AN-263 Sine Wave Generation Techniques (Rev. C)PDF, 747 Kb, 修订版: C, 档案已发布: Apr 22, 2013
This application note describes the sine wave generation techniques to control frequency amplitude anddistortion levels. - 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.
