The 24bit Audio CODEC series
Monaural Audio CODEC
with Touch Panel Interface
BU26154MUV
General Description
BU26154 is a low-power compact audio CODEC.
BU26154 also incorporates touch panel interface and
Cap-Less headphones amplifier, speaker amplifier which
is most suitable for digital still cameras, electronic
dictionaries. BU26154 has built-in voltage regulator for
the stability of CODEC characteristic that is sensitive to
the outside noise. Speaker amplifier that can change AB
/ D Class. Therefore, when the interference including the
FM radio influences it, BU26154 can prevent
interference by operating AB grade. As digital code
processing, it is equipped with the high-pass filter as the
noise cut use of the specific frequency band, Notch filter
and the Equalizer of 5 bands and P²Bass+, Noise gate,
and flexible sound quality effect processing is possible.
