LT1193 Video Difference Amplifier UFEATURESDESCRIPTIO ■ Differential or Single-Ended Gain Block (Adjustable) The LT®1193 is a video difference amplifier optimized for ■ –3dB Bandwidth, AV = ±2: 80MHz operation on ±5V and a single 5V supply. This versatile ■ Slew Rate: 500V/µs amplifier features uncommitted high input impedance (+) ■ Low Cost and (–) inputs, and can be used in differential or single- ■ Output Current: ±50mA ended configurations. Additionally, a second set of inputs ■ Settling Time: 180ns to 0.1% give gain adjustment and DC control to the differential ■ CMRR at 10MHz: > 40dB amplifier. ■ Differential Gain Error: 0.2% The LT1193’s high slew rate, 500V/µs, wide bandwidth, ■ Differential Phase Error: 0.08° 80MHz, and ±50mA output current make it ideal for ■ Single 5V Operation driving cables directly. The shutdown feature reduces the ■ Drives Cables Directly power dissipation to a mere 15mW and allows multiple ■ Output Shutdown amplifiers to drive the same cable. U The LT1193 is available in 8-pin PDIP and SO packages.
