NCP2823 Series
High Efficiency 3W
Filterless Class D Audio
Amplifier
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.
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.
