The NCP2820 is a cost-effective mono Class-D audio power amplifier capable of delivering 2.65W of continuous average power to 4 Ohm Bridge Tied Load from a 5V supply. Under the same conditions the output power stage can provide 1.4W to a 8 Ohm BTL load with less than 1% THD+N. For cellular handsets or PDAs it offers sapce 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. The NCP2820 processes analog inputs with a pulse width modulation technique that lowers output noise and THD when compared to a conventional sigma-delta modulator. The device allows independent gain while summing signals from various audio sources. Thus in cellular handsets the earpiece the loudspeaker and even the melody ringer can be driven with a single NCP2820. Due to its low 42uV noise floor A-weighted a clean listening is guaranteed no matter the load sensitivity.
