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.
Applications
Micro-component stereo systems, radio cassette players and mini-component stereo systems
Features
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.
