MA2304DNSXUMA1 is an ultra�low idle power, MERUS� multilevel switching class�D audio amplifier with integrated DSP and inductor�less operation. It features the MERUS� multilevel switching amplifier technology enabling unmatched power efficiency at both low and high output power. Multilevel switching also relaxes EMI and enables inductorless applications with lower cost and no compromise in audio performance or efficiency. A high order internal feedback loop ensures low THD for excellent audio performance. The integrated DSP offers a configurable processing flow and can be used to correct and tune real speaker applications with e.g. equalization, limiting, and more. Target application includes battery-powered speakers, Bluetooth/wireless/smart speakers and soundbars, conference speakers, and Multichannel/multi�room audio systems.
