NCP2820/D
NCP2820 Series
2.65 W Filterless Class-D
Audio Power Amplifier
The NCP2820 is a costeffective mono ClassD audio power
amplifier capable of delivering 2.65 W of continuous average power
to 4.0
W from a 5.0 V supply in a Bridge Tied Load (BTL)
configuration. Under the same conditions, the output power stage can
provide 1.4 W to a 8.0
W BTL load with less than 1% THD+N. For
cellular handsets or PDAs it offers space and cost savings because no
output filter is required when using inductive tranducers. 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 sigmadelta 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
42
mV noise floor, Aweighted, a clean listening is guaranteed no
matter the load sensitivity. With zero pop and click noise performance
NCP2820A turns on within 1 ms versus 9 ms for NCP2820 version.
