Video Difference Amplifier

The LT1194 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 uncommitted 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.
