NJM2573
PRELIMINARY LOW VOLTAGE 3ch VIDEO AMPLIFIER WITH LPF
s GENERAL DESCRIPTION The NJM2573 is a Low Voltage 3ch Video Amplifier with LPF. Internal 75 driver is easy to connect TV monitor directly. The NJM2573 corresponds to a clamp and bias inputs, and selection of a clamp/ bias is possible for one circuit, and it corresponds to various video signals. The NJM2573 features low power and small package, and is suitable for low power design on downsizing of DVC. sFEATURES q Operating Voltage q Input type s PACKAGE OUTLINE
