audioguru Posted December 16, 2006 Report Share Posted December 16, 2006 Most semiconductor manufacturers have class-D audio amplifier ICs that are very complicated inside.A class-D amplifier uses switching transistors and Pulse-Width-Modulation. The duty-cycle of the high frequency pulses determines the average output voltage and the position of the cone of a loudspeaker. The output transistors continuously switch fully on and fully off so that they don't produce much heat.Google has many articles like this one:ClassD.pdf Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted December 16, 2006 Report Share Posted December 16, 2006 The P channel needs to be on top, the N channel on the bottom. Quote Link to comment Share on other sites More sharing options...
audioguru Posted December 16, 2006 Report Share Posted December 16, 2006 The P channel needs to be on top, the N channel on the bottom.Confusing, isn't it?Wouldn't it be nice if everybody drew the symbol for a Mosfet the same way? Quote Link to comment Share on other sites More sharing options...
