LT6550/LT6551

3.3V Triple and Quad

Video Amplifiers

FEATURES

DESCRIPTIO

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.

Input Common Mode Range Includes Ground

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.
