DESCRIPTION

The MA2304DNS is a 2x37 W audio amplifier with inte grated audio DSP and 12S/TDM audio interface. 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 inductor-less applications with lower cost and no compromise in audio performance or efficiency. A high or-derinternal 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. The ultra-low idle power consumption is at least five times lower than the traditional class D audio amplifiers in the market, making MA2304DNS ideal for battery powered speaker applications with extended battery life and/or reduced battery cell cost. In mains-powered multichannel ap-plications, the reduced and scalable EMI performance, enables otherwise impossible industrial designs, without the necessity for a heatsink or a traditional LC filter.

FEATURES

MERUS? multilevel switching technology
