Audio ICs
Built-in BBE螜螜 Audio sound controller
BD3860K
BD3860K can reproduce clear sound in high band and distinct sound in low band by integrating BBE螜螜 function.
If this IC is used for car stereo, sound can be reproduced distinctly without turning up the volume.
!
Applications
Car audio, Mini component, Micro component.

Features
1) Built-in BBE螜螜 circuit, 4-input selector (4ch stereo), input gain, main volume, loudness, tone (2 band), fader volume.
2) BBE螜螜 circuit is profitable for S/N because of no process control in no signal.
3) Bi-CMOS process is suitable for the design of low current and energy saving. It provides more quality for small scale
regulator and heat in a set.
4) Q factor, center frequency f
0
, and gain G of bass can be controlled by external parts. These functions can be used as
super bass filter.
5) Can be controlled by power supply of 3.3V or 5V.
6) Easy to design signal level diagram by laying BBE螜螜, and tone circuit through main volume.
7) Easy layout of the board by laying each pin of audio input (total 8pin), and audio output (total 4pin) together.
