Class D Audio Amplifier Output Filter Optimization



关键词: Class D, audio amplifiers, switching amplifier, output filter, modulation noise, PWM, filterless, amplifiers, amplifer 


Abstract: This application note examines the effect of the output filter on audio Class D amplifier performance. Switch-mode amplifiers such as the MAX4295 and MAX4297 offer improved efficiency over their more traditional Class AB counterparts. By understanding the operation of these devices, the modulation noise spectrum and the loudspeaker loads they are required to drive, it is possible to completely eliminate the output filter while retaining the efficiency benefits of Class D amplifiers.
