Class-D LC Filter Design (Rev. A)

An LC filter is critical in helping you reduce electromagnetic radiation (EMI) of Class-D amplifiers. In some Class-D amplifiers, you also need the LC filter to ensure high efficiency outputs. This application report presents the implementations and theories of LC filter design for Class-D audio amplifiers using the AD (Traditional) and BD (Filter Free) Class-D modulation designs.
