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.
