LT6553 - 650MHz Gain of 2 Triple Video Amplifier

The LT®6553 is a high-speed triple video amplifier with an internally fixed gain of 2. The individual amplifiers are optimized for performance with a double terminated 75 Ohm video load and feature a 2VP–P full signal bandwidth of 400MHz, making them ideal for driving very high-resolution video signals. Separate power supply pins for each amplifier boost channel separation to 75dB, allowing the LT6553 to excel in many high-speed applications.

While the performance of the LT6553 is optimized for dual supply operation, it can also be used on a single supply as small as 4.5V. Using dual 5V supplies, each amplifier draws only 8mA. When disabled, the amplifiers draw less than 100µA and the output pins become high impedance. Furthermore, the amplifiers are capable of turning on in less than 50ns, making them ideal for multiplexing and portable applications.

The LT6553 is manufactured on Linear Technology’s proprietary low voltage complementary bipolar process and is available in the 16-lead SSOP package that fits in the same PCB area as an SO-8 package.
