Description
The AD724 is a complete RGB to S-Video converter on a chip, requiring just a few minor external components.
Building Your Own RGB To Composite Converter
The AD724 is only available in an SMD package. You can choose to make the entire PCB in SMD or use standard parts for the external components.
Schematic
The following schematics are configured for PAL TVs. If you are in an area where NTSC is in use, please see the note below regarding pinout changes.

NTSC
Pin 1 of the AD724 selects whether the output is in PAL or NTSC format. In the schematics and layouts above, pin 1 is grounded to select PAL, should you require NTSC, this pin needs to be disconnected from the ground and connected to a 5V signal.
