Description
The LT1187 is a difference amplifier optimized for operation on ±5V, or a single 5V supply, and gain ³2. 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 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.
