Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

However, no responsibility is assumed for its use. Linear Technology Corporation makes no represen-

tation that the interconnection of its circuits as described herein will not infringe on existing patent rights.

The LT

internally fixed gain of 2. The individual amplifiers are

optimized for performance with a double terminated 75

Ω

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

µA 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’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.
