NJU71074
OUTPUT COUPLING CAPACITOR-LESS
LOW VOLTAGE VIDEO AMPLIFIER WITH LPF,Y/C MIX
GENERAL DESCRIPTION
The NJU71074 is a Low Voltage Video Amplifier with LPF,Y/C MIX
circuit. By the internal charge pump circuit, output capacitor is
unnecessary.
The NJU71074 features low power and small package, and is
suitable for low power design on downsizing of portable video
system and system with video output.
