excellent audio characteristics of the NCP4894 are a guarantee of a
high quality sound, for example, in mobile phones applications. With
a 10% THD+N value the NCP4894 is capable of delivering 1.8 W of
continuous average power to an 8.0 W load from a 5.5 V power
supply. With the same load conditions and a 5.0 V battery voltage, it
ensures 1.0 W to be delivered with less than 0.01% distortion.
