All rights reserved. 23.Jun.2014 Rev.001 TSZ22111 • 14 • 001 www.rohm.com 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 P 2Bass+, Noise gate, and flexible sound quality effect processing is possible. Features ■ Various sound processing functions P 2Bass+ Noise gate Fast release ALC 5-band Equalizer/Notch Filter ■ High PSRR is attained by built-in regulator ■ Speaker amplifier can be switched to AB class and D class. ■ Touch panel interface. Applications ■ Electronic Dictionary ■ Digital Still Camera ■ Digital Single-lens Reflex Camera ■ Digital Mirror-less Camera ■ Digital Video Camera, others Key Specifications ■ HVDD Power Supply: 2.7V to 3.6V SPVDD Power Supply: 2.7V to 5.5V CPDD Power Supply: 2.7V to 3.6V TVDD Power Supply: 2.7V to 3.6V MIC-ADC SNR: 92dB(Typ) DAC-SP SNR: 95dB (Typ) DAC-HP SNR t: 93dB (Typ) Package(s) W (Typ) x D (Typ) x H (Max) VQFN040V6060 6.00mm x 6.00mm x 0.50mm Typical Application Circuit(s) Figure 1.
