Web9 mrt. 2024 · As discussed above, designing the LC low-pass filter for a class D amp is not particularly straightforward. The FDA901 attempts to improve this aspect of class D implementation by means of a feedback topology that ST describes as “innovative.”. The basic idea here is that the LC filter is included inside the amplifier’s feedback loop ... Web9 jan. 2008 · The heart of a Class-D amplifier filter is a L-C low-pass filter. The corner frequency of the filter is chosen so that the filter will have minimal effect on the desired output frequency range while attenuating the switching noise as much as possible.
