BD3861FS  
Audio ICs  
Audio sound controller  
BD3861FS  
The BD3861FS is an audio sound controller IC for micro-component stereo systems. Tone and volume can be controlled  
easily by two-line serial control from micro-controller.  
zApplications  
Micro-component stereo systems, radio cassette players and mini-component stereo systems  
zFeatures  
1) Built-in volume, tone (bass, middle and treble), input gain amplifier and input selector.  
2) The volume control of resistance ladder type allows the low distortion and low noise in Bi-CMOS process.  
3) Two-line serial interface.  
4) The built-in input gain amplifier reduces the needs of external input, and this IC is suitable for space-saving design.  
5) Residual noise can be reduced by separating the front stage volume control from the rear stage volume control.

zOperation notes  
1. About operation voltage supply range  
Within operation voltage supply range, basic circuit function operation is guaranteed within operation ambient  
temperature. But please confirm set up of constant and element, voltage set up and temperature set up on use.  
2. About operation temperature range  
If it within recommended operation voltage range, circuit function operation is guaranteed within operation temperature.  
It corralled to conditions of power dissipation to temperature.  
Please watch out except condition stipulated by electrical characteristics within the range, It cannot guarantee standard  
value of electrical characteristics. But it retains original function.  
3. About Application circuit  
Example of application circuit drawing is convinced as recommendable, but please confirm characteristic including  
above-mentioned notes. At use with modification of external constant, please decide with enough margin considering  
distribution of this IC, external parts including quiescence characteristics and excessive characteristics. Please note  
that we have not yet confirmed any concerned patent rights completely.  
4. Power-on reset  
Any circuit to perform initialization in the IC upon power on is not contained. Therefore, be sure to send initial data to all  
the addresses upon power on. Moreover, be sure to mute the set side until the initial data has been sent. For data  
setting at the second time or later, necessary address only can be modified.  
5. Schmidt circuit  
This IC has the Schmidt circuit as preventive measures against logic signal input into the DATA (14pin) and CLK  
(15pin) terminals. Therefore, this IC is not affected so much by noise to a logic signal line. For the “High” voltage for  
logic control, voltage in a range from 2.6 to 5.5V is available.  
6. Setting of input gain  
Because of the S/N characteristics, it is recommendable to turn ON 6dBSW in input gain in a range between 6 and  
20dB (in 2dB increment).  
7. Input pin E1 (9pin) and E2 (10pin)  
Input pin E1 (9pin) and E2 (10pin) has a built-in mute circuit. It is the optimal for the auxiliary input.  
8. Microphone terminal  
If the microphone terminal (11pin) is not used, use this IC in “open” because of the S/N characteristics.  
9. Serial control  
Wire the CLK terminal and DATA terminal taking care not to interfere with an analog signal line.
