The LT1189 is a difference amplifier optimized for opera-
tion on 5V, or a single 5V supply, and gain 10. This
versatile amplifier features uncommitted high input im-
pedance (+) 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 LT1189’s high slew rate, 220V/ s, wide bandwidth,
35MHz, 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 LT1189 is a low power, gain of 10 stable version of the
popular LT1193, and is available in 8-pin miniDIPs and SO
packages. For lower gain applications see the LT1187
data sheet.
