Using class D amplifiers in portable apps

Posted: 14 Nov 2012 ?? ?Print Version ?Bookmark and Share

Keywords:Class D amplifiers? portable applications? battery?

Class D amplifiers are generally efficient, making them ideal candidates for portable applications that require long battery life and low thermal dissipation. However, electromagnetic interference (EMI) is an issue that commonly accompanies the Class D switching topology. Active emissions limiting reduces radiated emissions and enables "filterless" operation, allowing designers to create small, efficient portable applications with low EMI.
