The 24bit Audio CODEC series

Monaural Audio CODEC

with Touch Panel Interface

BU26154MUV

General Description

Key Specifications

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.
