NJM2795
Ground noise isolation Amplifier
with Adjustable Differential Gain
GENERAL DESCRIPTION
The NJM2795 is a ground noise isolation amplifier. It
contains dual channel differential amplifier with Adjustable
Differential Gain.
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.
Further the NJM2795 allow the user to alter the gain to
optimize the signal-to-noise ratio of their system. It is useful
in microphone amplifier applications.
