This document provides EMC output filter recommendations that are tailored to the MERUS™ MA12040,MA12040P, MA12070 and MA12070P audio amplifiers. The recommendations are a guideline to pass EMC tests for various applications. They are not covering every situation as every product or application is different. The potential to choose and combine components is vast, and the final solution will constitute a tradeoff between size, price, filter characteristics and performance.
