Typical Application
Description
The LT6554 is a high-speed triple video buffer with an internally fixed gain of 1. The individual buffers are optimized for performance with a 1k load and feature a 2VPP 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 90dB, allowing the LT6554 to excel in many high speed applications.
While the performance of the LT6554 is optimized for dual supply operation, it can also be used on a single supply as low as 4.5V. Using dual 5V supplies, each amplifier draws only 8mA. When disabled, the amplifiers draw less than 100µA and the outputs become high impedance. Furthermore, the amplifiers are capable of turning on in less than 50ns, making them suitable for multiplexing and portable applications.
The LT6554 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.
