In summary, Infineon’s MERUS™ multi-level class D amplifier technology is much more efficient than conventional class D amplifiers. Its 52 mW low idle power and higher light load music playback efficiency enables battery powered systems with extend running time and reduces system heat generation both in battery powered applications and AC-power applications. The induct-less filtering solution minimizes system PCB area and saves filter cost, while offering better EMI performance for easy development. MA2304 is the latest MERUS multi-level class D amplifier from Infineon and its supporting tools and documents can easily be accessed online.
