Ground Noise Isolation Amplifier
■ GENERAL DESCRIPTION
The NJM2794 is a ground noise isolation amplifier
designed for car audio system. It contains dual channel
differential amplifier.
It is developed for those car audio applications where long
connections between head unit and other components are
necessary and ground noise has to be eliminated.
■ FEATURES
