DESCRIPTION

The MA2304PNS is a 2x37 W audio amplifier with 125/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 order internal feedback loop ensures low THD for excellent audio performance. The ultra-low idle power consumption is at least five times lower than the traditional class D audio amplifiers in the market. mak ing MA2304PNS ideal for battery powered speaker applications with extended battery life and/or reduced battery cell cost. In mains-powered multichannel applications, 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

• 5-level voltage modulation for ultra-low idle power con-

sumption: 52 mW @ 18 PVDD (LPC mode) without the

need of complex dynamic rail-tracking systems

• Inductor-less application for reduced system cost without output power limitations

• Reduced EMI emissions compared to traditional 2 and 3

level class D audio amplifiers for fast time to market with-out compromises in audio performance or efficiency

• High efficiency at low output power: 79 , 2x1 W, 8 02

for extended battery life and easy thermal management
