Class-D Amplifier Design Considerations
3.3 Class-D Amplifier Design Considerations
Detailed information for proper design and implementation of TI class-D audio power amplifiers appears in the application report Design Considerations for Class-D Audio Power Amplifiers, TI Literature Number SLOA031, on the TI website (http://www.ti.com/sc/apa). This document provides background information, general equations, and component selection criteria for the topics listed below. General layout considerations are also included in the report.
-Class-D amplifier circuits (input, output, charge pump, and switching)
-Control and indicator circuits
-Power supply decoupling
The application report Reducing and Eliminating the Class-D Output Filter, SLOA023, is also available from the website, and provides information to help determine what type of output filter, if any, may be necessary.
