The LT
®
1193 is a video difference amplifier optimized for
operation on ±5V and a single 5V supply. This versatile
amplifier features uncommitted high input impedance (+)
and (–) inputs, and can be used in differential or single-
ended configurations. Additionally, a second set of inputs
give gain adjustment and DC control to the differential
amplifier.
The LT1193’s high slew rate, 500V/µs, wide bandwidth,
80MHz, and ±50mA output current make it ideal for
driving cables directly. The shutdown feature reduces the
power dissipation to a mere 15mW and allows multiple
amplifiers to drive the same cable.
The LT1193 is available in 8-pin PDIP and SO packages.
