MERUS? multilevel switching technology

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

sumption: 155 mW @ 24 PVDD without the need of com-

plex 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
