NCP2821
2.65 W Filterless with
Selectable Gain ClassD
Audio Amplifier
NCP2821 is a cost effective mono audio power amplifier designed
for portable communication device applications such as mobile
phones. The internal gain setting between 6 dB and 12 dB will also
save external gain setting resistors. To achieve a typical audio mono
application, you only need an external capacitor for filtering the power
supply. The NCP2821 processes analog inputs with a PWM technique
that lowers significantly output noise and THD.
This part is capable of delivering 2.65 W of continuous average
power to a 4.0
W BTL load from a 5.0 V power supply. Operating on a
single 3 V supply, the output power stage can provide 500 mW to an
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 transducers. Its improved ClassD
technology makes it suitable for portable devices. With 90%
efficiency and very low shutdown current, it increases widely the
lifetime of your battery compared to a ClassAB solution. It also
minimizes the junction temperature.
It fully rejects “pop & click” noises with a fast startup time of 9 ms.
Added to a 65 dB PSRR, the NCP2821 audio power amplifier is
specifically designed to provide high quality output power from low
supply voltage, requiring only 1 external capacitor.
