NJU71031
OUTPUT COUPLING CAPACITOR-LESS
LOW VOLTAGE VIDEO AMPLIFIER WITH LPF
Q GENERAL DESCRIPTION
The NJU71031 is a Low Voltage Video Amplifier with LPF circuit.
By the internal charge pump circuit, output capacitor is unnecessary.
The NJU71031 features low power and small package, and is
suitable for low power design on downsizing of portable video
system and system with video output.
