DESCRIPTIO

EATURE

■

Differential or Single-Ended Gain Block (Adjustable)

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.

Low Cost

The LT1189’s high slew rate, 220V/µs, 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.
