LT1193 Video Difference Amplifier FEATURES DESCRIPTIO n Differential or Single-Ended Gain Block (Adjustable) The LT 1193 is a video difference amplifier optimized for n 3dB Bandwidth, A = 2: 80MHz operation on 5V and a single 5V supply. This versatile V n Slew Rate: 500V/m s amplifier features uncommitted high input impedance (+) n Low Cost and () inputs, and can be used in differential or single- n Output Current: 50mA ended configurations. Additionally, a second set of inputs n Settling Time: 180ns to 0.1% give gain adjustment and DC control to the differential n CMRR at 10MHz: > 40dB amplifier. n Differential Gain Error: 0.2% The LT1193s high slew rate, 500V/m s, wide bandwidth, n Differential Phase Error: 0.08 80MHz, and 50mA output current make it ideal for n Single 5V Operation driving cables directly. The shutdown feature reduces the n Drives Cables Directly power dissipation to a mere 15mW and allows multiple n Output Shutdown amplifiers to drive the same cable. U The LT1193 is available in 8-pin PDIP and SO packages.
