Features

Built-in isolator function for Audio/Video input channels

Car navigation systems, car DVD players, and car audio systems have concern with automotive noises that generated by electronic systems. These noises interrupt into devices as noise current via chassis, but ROHM's IC enables noise elimination with Amplifier's characteristics of common-mode input.
