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 voltagesвЂ”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 ampliп¬Ѓer supply voltage, we must п¬Ѓrst 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 …

DESIGN FEATURES Triple and Quad RGB Amplifiers
Deliver Full Performance on 3.3V
by Jon Munson and Raj Ramchandani
Introduction Amplifier Characteristics
The block diagrams in Figure 1 show
the differences between the LT6550
and LT6551. The LT6551 quad is
designed for single supply operation
with the feedback returned to ground.
The LT6550 triple has a separate VEE
pin and can be used on either single
or split supplies.
These devices feature internal feedback resistors and a flow-thru pin out,
