3.3V Triple and Quad
Video Amplifiers
The LT
®
6550/LT6551 are 3.3V triple and quad high speed
video amplifiers. These voltage feedback amplifiers drive
double terminated 50Ω or 75Ω cables and are configured
for a fixed gain of 2, eliminating six or eight external gain
setting resistors. The LT6550/LT6551 feature 110MHz
–3dB bandwidth, high slew rates and fast settling, making
them ideal for RGB video processing.
The LT6551 quad is designed for single supply operation
and the LT6550 triple can be used on either single or split
supplies. On a single 3.3V supply, the input voltage range
extends from ground to 1.55V and the output swings to
within 400mV of the supply voltage while driving a 150Ω
load. These features, combined with the ability to accept
RGB video signals without the need for AC coupling or
level shifting of the incoming signals, make the LT6550/
LT6551 an ideal choice for low voltage video applications.
Both the LT6550 and LT6551 are available in the small
10-Pin MSOP package and utilize a flow-thru pin out. The
small footprint results in a compact high performance
video amplifier solution.
