NJM2525
4CH VIDEO AMPLIFIER WITH SW&SD/ HD LPF
s
GENERAL DESCRIPTION
The
NJM2525
is 4ch video amplifier with SD/HD LPF.
The
NJM2525
includes 2in-1out selector for the composite and
component signal. The isolation amplifier eliminates the common
mode noise from external equipment.
The
NJM2525
is suitable for the AV equipment such as the home
theater systems and AV receivers that switch the internal Video signal
and the external Video signal.
