LT6555
650MHz Gain of 2 Triple
2:1Video Multiplexer
DESCRIPTIO
The LT®6555 is a high speed triple 2:1 video multiplexer
with an internally fixed gain of 2. The individual amplifiers
are optimized for performance with a double terminated
75⦠video load and feature a â3dB 2VP-P bandwidth of
450MHz, making them ideal for driving very high resolu-
tion video signals. Separate power supply pins for each
amplifier boost channel separation to 72dB, allowing the
LT6555 to excel in many high speed applications.
While the performance of the LT6555 is optimized for dual
supply operation, it can also be operated with a single
supply as low as 4.5V. Using dual 5V supplies, each
amplifier draws only 9mA. When disabled, the amplifiers
draw less than 500µA and the outputs become high
impedance.
The LT6555 is manufactured on Linear Technologyâs
proprietary low voltage complementary bipolar process
and is available in 24-lead SSOP and ultra-compact
24-lead QFN packages.
