The LT

internally fixed gain of 1. The individual buffers are opti-

mized for performance with a 1k load and feature a

for driving very high-resolution video signals. Separate

power supply pins for each amplifier boost channel sepa-

ration 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. Further-

more, 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.
