NCP2823 Series  
High Efficiency 3W  
Filterless Class D Audio  
Amplifier  
The NCP2823A/B are cost effective mono audio power amplifiers  
designed for portable electronic devices. NCP2823A is optimized for  
8 W operation and NCP2823B can operate with speaker impedance  
down to 4.0 W. For Instance, NCP2823B is capable of delivering 3 W  
of continuous average power to a 4.0 W from a 5.0 V supply in a  
Bridge Tied Load (BTL) configuration. Under the same conditions,  
NCP2823A can provide 1.5 W to an 8.0 W BTL load with less than  
10% THD+N. For cellular handsets or PDAs it offers space and cost  
savings because no output filter is required when using inductive  
transducers. With more than 90% efficiency and very low shutdown  
current, it increases the lifetime of your battery and drastically lowers  
the junction temperature.  
NCP2823 processes analog inputs with a pulse width modulation  
technique that lowers output noise and THD. The device allows  
independent gain while summing signals from various audio sources.  
Thus, in cellular handsets, the earpiece, the loudspeaker and even  
melody ringer can be driven with a single NCP2823. Due to its low  
26 mV noise floor, A−weighted, clean listening is guaranteed no matter  
the load sensitivity.
