The AD725 is a very low-cost, general-purpose RGB-to-NTSC/PAL encoder that converts red, green, and blue component signals into corresponding brightness (baseband amplitude) and chromatic (subcarrier amplitude and phase) signals that meet NTSC or PAL standards. At the same time, the two outputs are combined on-chip to provide a composite video output. All three outputs can be used independently and are voltage twice the standard signal level required to drive a 75 Ω reverse terminated cable.
