LT1187 Low Power Video Difference Amplifier FEATURES DESCRIPTION n Differential or Single-Ended Gain Block (Adjustable) The LT 1187 is a difference amplifier optimized for opera- n 3dB Bandwidth, A = 2: 50MHz tion on 5V, or a single 5V supply and gain 2. This ver- V n Slew Rate: 165V/s satile amplifier features uncommitted high input imped- n Low Supply Current: 13mA ance (+) and () inputs, and can be used in differential or n Output Current: 20mA single-ended configurations. Additionally, a second set n CMRR at 10MHz: 40dB of inputs give gain adjustment and DC control to the dif- n LT1193 Pin Compatible ference amplifier. n Low Cost The LT1187s high slew rate, 165V/s, wide bandwidth, n Single 5V Operation 50MHz, and 20mA output current require only 13mA of n Drives Cables Directly supply current. The shutdown feature reduces the power n Output Shutdown dissipation to a mere 15mW and allows multiple ampli- n Available in 8-Lead PDIP and SO Packages fiers to drive the same cable. The LT1187 is a low power version of the popular LT1193, APPLICATIONS and is available in 8-pin miniDIPs and SO packages.
