DESCRIPTION

Low Power

Video Difference Amplifier

The LT

eration on ±5V, or a single 5V supply and gain ≥2. This

versatile amplifier features uncommitted high input imped-

ance (+) 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

difference amplifier.

The LT1187’s high slew rate, 165V/ms, wide bandwidth,

50MHz, and ±20mA output current require only 13mA of

supply current. The shutdown feature reduces the power

dissipation to a mere 15mW and allows multiple amplifiers

to drive the same cable.

The LT1187 is a low power version of the popular LT1193,

and is available in 8-pin miniDIPs and SO packages. For

applications with gains of 10 or more, see the LT1189

data sheet.
