LT1189 Low Power Video Difference Amplifier Features s s s s s s s s s s s DESCRIPTIO Differential or Single-Ended Gain Block (Adjustable) - 3d B Bandwidth, AV = ± 10 35MHz Slew Rate 220V/µs Low Supply Current 13m A Output Current ± 20m A CMRR at 10MHz 48d B LT1193 Pin Out Low Cost Single 5V Operation Drives Cables Directly Output Shutdown The LT1189 is a difference amplifier optimized for operation on ± 5V, or a single 5V supply, and gain ≥ 10. This versatile amplifier Features unmitted 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 ± 20m A output current require only 13m A of supply current. The shutdown feature reduces the power dissipation to a mere 15m W, and allows multiple amplifiers 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.
