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.

Features
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.
3) Control through I2C BUS serial control.
4) Internal pseudo-stereo circuit provides phase-shift matrix surround effect.

Applications
    DVDs, personal computers, high-vision TVs, karaoke sets, digital broadcasts, CATVs, and other TV equipment
