Product Introduction

Overview

The AD724JRZ, produced by Analog Devices Inc., is a low-cost RGB to NTSC/PAL Encoder. This integrated circuit converts red, green, and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals, adhering to either NTSC or PAL video standards. The device provides composite video output and separate Y/C (S-Video) outputs, making it versatile for various video encoding applications. It operates from a single +5 V supply and does not require external delay lines or filters, simplifying the design process. The AD724JRZ is available in a compact 16-lead SOIC package and is specified for the 0°C to +70°C commercial temperature range.
