NJM41050
47µF AC-Coupling Capacitor
3-Input 1-Output Video Driver with LPF
s GENERAL DESCRIPTION
The NJM41050 is a 3-Input 1-Output general-purpose video switch.
It includes 6dB amplifier and 75ohm driver circuit. The NJRC original
Technology “ASC(Advanced SAG Correction)” realizes 47µF AC-Coupling
Capacitor which enables to downsize mounting space.
