DESCRIPTION
Video Difference Amplifi er
The LT
eration on ±5V, or a single 5V supply and gain ≥2. This
versatile amplifi er features uncommitted high input imped-
ance (+) and (–) inputs, and can be used in differential
or single-ended confi gurations. Additionally, a second
set of inputs give gain adjustment and DC control to the
difference amplifi er.
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 amplifi ers
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.
