NJM2570A - Video Amplifier

General Description

NJM2570A is a video amplifier included LPF in Y and C system.

Adjustable LPF characteristic with external resistor and output with 75ohm driver optimize the TV monitor system.

Also, it can discriminated the aspect ratio of TV by internal DC interface for S terminal.
