Description
AI
The LT1189 is a difference amplifier optimized for operation on ±5V, or a single 5V supply, and gain ≥10. 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 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 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 mini DIPs and SO packages. For lower gain applications see the LT1187 data sheet.ApplicationsLine ReceiversVideo Signal ProcessingCable DriversTape and Disc Drive Systems
