BD37531FV
3-band 이퀄라이저 내장 사운드 프로세서
세트 설계 효율 향상을 목적으로, 제어 소프트웨어의 공통화와 기판의 공통화를 실현한 시리즈입니다. 외장 부품이 적은 스페이스 절약 타입으로, 3-band parametric 이퀄라이저에 의한 음질 조정이 가능합니다. 카 오디오에 필요한 기능을 구비하여 고성능 특성을 실현하였습니다. 스탠다드한 세트에서 서브 우퍼 출력 단자를 확장 단자로도 사용하는 카 오디오 세트에 최적입니다.

특징 :
- Reduce switching noise of input gain control, mute, main volume,
fader volume, bass, middle, treble, loudness, by using advanced switch circuit
[Possible to control all steps] - Built-in ground isolation amplifier inputs, ideal for external stereo input.
- Built-in differential input selector that can make various combination of
single-ended / differential input. - Built-in input gain controller reduce switching noise for volume of
a portable audio input. - Decrease the number of external components by
built-in 3-band equalizer filter, loudness filter,
And, possible to control Q, Gv, fo of 3-band equalizer
and fc of LPF,and fo, Gv of loudness by I²C BUS control freely. - It is possible for the bass, middle, treble to the gain adjustment
quantity of ±20dB and 1 dB step gain adjustment. - It is equipped with output terminals of Subwoofer.
Moreover, the stereo signal of the front and rear also can be
output by the I²C BUS control. - Bi-CMOS process is suitable for the design of low current and low energy.
And it provides more quality for small-scale regulator and heat in a set. - Package is SSOP-B28. Putting input-terminals together and
output-terminals together can make PCB layout easier
and can makes area of PCB smaller. - It is possible to control by 3.3V / 5V for I²C BUS.
