of Digital Audio Amplifier ICs
N
owadays, digital audio ampli-
fier ICs are being used as au-
dio amplifiers for digital au-
dio-video (A/V) devices such
as mobile phones, portable audio play-
ers, and flat-panel LCD TVs primarily
because of their lower power consump-
tion and less heat generation. They also
have the capacity to support the creation
of smaller circuits rather than using con-
ventional linear amplifiers while achiev-
ing the same level of audio performance,
including sound quality and distortion.
