    Filter-Free Class-D Audio Amplifiers
    Traditional Class-D amplifiers lose efficiency if they do not use output LC filters. Texas Instruments offers many Class-D amplifiers that are designated Filter-Free. This means they do not require an output LC filter to maintain high efficiency. However, in some cases an LC or ferrite bead filter is required for EMC.
