  Video Signal Distribution Using Low Supply Voltage Amplifiers
  Design Note 327
  Jon Munson
  Introduction
  Video designs are often pressed to operate on the lowest
  possible rail voltages—a simple result of the trend towards lower voltage logic and the advantages of sharing
  supply potentials wherever possible. Video designs are
  further complicated by the need to accommodate the
  dynamic offset variation inherent in AC-coupled designs
  as picture content varies. Traditional op amps require
  relatively large amounts of output-swing headroom and
  are therefore impractical for AC coupling at even 5V.
  Linear Technology offers a new family of video op amps
  which addresses these issues and offers the ability to
  operate down to 3.3V in most instances. This family
  includes the LTВ®6205 (single), LT6206 (dual), LT6207
  (quad), LT6550 (triple, п¬Ѓxed gain of 2) and LT6551
  (quad, п¬Ѓxed gain of 2).
  Video Signal Characteristics
  To determine the minimum video amplifier supply voltage, we must first examine the nature of the signal.
  Composite video is the most commonly used signal
  in broadcast-grade products and combines Luma (or
  luminance, the intensity information), Chroma (the colorimetry information) and Sync (vertical and horizontal …
