Description

The LT®6550/LT6551 are 3.3V triple and quad high speed video amplifiers. These voltage feedback amplifiers drive double terminated 50 Ohm or 75 Ohm 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 150 Ohm 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.
