internally fixed gain of 2. The individual amplifiers are
optimized for performance with a double terminated 75鈩?/div>
video load and feature a 2V

full signal bandwidth of
400MHz, making them ideal for driving very high-resolu-
tion 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 100碌A(chǔ) and the EN pin and output pins become high
impedance. Furthermore, the amplifiers are capable of
turning on in less than 50ns, making them ideal for spread
spectrum and portable applications.
The LT6553 is manufactured on Linear Technology鈥檚
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.
