NJM2573
LOW VOLTAGE 3ch VIDEO AMPLIFIER WITH LPF
s GENERAL DESCRIPTION
The NJM2573 is a Low Voltage 3ch Video Amplifier with LPF.
Internal 75Ω 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.
