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.
