DESCRIPTIO
The LT
internally fixed gain of 1. The individual buffers are opti-
mized for performance with a 1k load and feature a
2V
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.
