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.
