www.DataSheet4U.com BH3865S Video ICs Dual-line serial control sound processor IC BH3865S The BH3865S 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. Note : I2C BUS is a registered trademark of Philips. !Applications DVDs, personal computers, high-vision TVs, karaok.

BH3865S Features

* 1) 2-channel volume and sound quality control. 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.
