Product Summary

The AD725ARZ is a very low cost general purpose RGB to NTSC/ PAL encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined on-chip to provide a composite video output. All three outputs are available separately at voltages of twice the standard signal levels as required for driving 75 W, reverse-terminated cables. The application of the AD725ARZ include RGB/VGA to NTSC/PAL Encoding, Personal Computers/Network Computers, Video Games, Video Conference Cameras, Digital Still Cameras.
