NJM2559
Output Coupling Capacitor-less Video Amplifier
with Power Supply Short-circuit Protection
GENERAL DESCRIPTION
The NJM2559 is a output coupling capacitor-less video amplifier
with power supply short-circuit protection.*
When the DC voltage is impressed to the output terminal, it
becomes a power saving mode, and IC is protected.
The NJM2559 is suitable for the video application at risk of power
supply short-circuit.
*DC coupling. You must not connect an output capacitor.
FEATURES
Operating Voltage 4.5 to 5.5V

APPLICATION
Please connect the capacitor of power supply terminal (pin 5) near IC.
You must not connect an output capacitor.
External resistance must use power dissipation :125mW or more.
When 120x3 are replaced with 360, 400mW or more is recommended.
