NCP2820: Audio Power Amplifier, Class D, 2.65 W, Filterless, Mono
For complete documentation, see the data sheet
Product Description
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.
