BH3866AS  
The BH3866AS is a signal processing IC developed for the control of volume and tone quality in TV equipment.  
Since dual-line serial control (I2C BUS) is used, the volume level and tone quality in TV equipment can be changed  
using signals such as those from a microcomputer or similar device.  
Applications  
DVDs, personal computers, high-vision TVs, karaoke sets, digital broadcasts, CATVs, and other TV equipment  
Features  
3) Control through I2C BUS serial control.  
4) Internal pseudo-stereo circuit provides phase-shift  
matrix surround effect.  
1) 3-channel volume and sound quality control (for  
stereo and center speakers).  
2) Absorption of volume deviation between input  
sources and improved S / N ratio, for better sound  
quality, using an AGC circuit.
