for complete modules check h**p://w*w.tripath.com/
or TI webside for TAS50xx chips like h**p://focus.ti.com/docs/prod/productfolder.jhtml?genericPartNumber=TAS5010

pwm amplifier

National manufactures an integrated circuit (LM4651/LM4652) that may be of your interest. They have a demo board and some theory at www.national.com/appinfo/audio/0,1819,968,00.html They send samples too.

Thank you all!

I would suggest the book "power amplifiers ..." of S.Crips. I think that it
is very good for understanding the theory and design practices of power amplifiers.

Best regards,

Theory may be seen on the:
hem.passagen.se/johanps/audioexperiment/class_D.htm

Simple schematics:
hem.passagen.se/johanps/audioexperiment/Amp21/DesignDescription21.htm

by the way,
has anyone good idea of how to realize class D amp
with digital modulation in DSP???? (i mean really the professional way)

maximum interest in that

 

[Etoja]

DSP version is more expensive and sound quality is bad in comparison with analog version.

Read theory: hem.passagen.se/johanps/audioexperiment/class_D.htm

to mimoto,
What is the contents of the book "power amplifiers ..." of S.Crips. ? Or can you upload that book here ?
