with Power Supply Short-circuit Protection

sGENERAL 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.
