DESCRIPTIO
The LT®1194 is a video difference amplifier optimized for
operation on ±5V and a single 5V supply. The amplifier has
a fixed gain of 20dB and features adjustable input limiting
to control tough overdrive applications. It has uncommit-
ted high input impedance (+) and (–) inputs, and can be
used in differential or single-ended configurations.
The LT1194’s high slew rate 500V/µs, wide bandwidth
35MHz, and ±50mA output current make it ideal for
driving cables directly. This versatile amplifier is easy to
use for video or applications requiring speed, accuracy
and low cost.
The LT1194 is available in 8-pin PDIP and SO packages.
