24bit Audio CODEC with Touch I/FADC - BU26154MUV

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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
