LT6553 650MHz Gain of 2 Triple Video Amplifier FEATURES DESCRIPTIO n 650MHz 3dB Small Signal Bandwidth The LT 6553 is a high-speed triple video amplifier with an n 400MHz 3dB 2V Large Signal Bandwidth internally fixed gain of 2. The individual amplifiers are P-P n 150MHz 0.1dB Bandwidth optimized for performance with a double terminated 75 n High Slew Rate: 2500V/s video load and feature a 2V full signal bandwidth of PP n Fixed Gain of 2 Requires No External Resistors 400MHz, making them ideal for driving very high-resolu- n 75dB Channel Separation at 10MHz tion video signals. Separate power supply pins for each n 50dB Channel Separation at 100MHz amplifier boost channel separation to 75dB, allowing the n 82dBc 2nd Harmonic Distortion at 10MHz, 2V LT6553 to excel in many high-speed applications. P-P n 72dBc 3rd Harmonic Distortion at 10MHz, 2V P-P While the performance of the LT6553 is optimized for dual n Low Supply Current: 8mA per Amplifier supply operation, it can also be used on a single supply as n 6ns 0.1% Settling Time for 2V Step small as 4.5V. Using dual 5V supplies, each amplifier n TTL Compatible Enable I 100A when Disabled SS draws only 8mA. When disabled, the amplifiers draw less n Differential Gain of 0.022%, Differential than 100A and the output pins become high impedance. Phase of 0.006 Furthermore, the amplifiers are capable of turning on in n Wide Supply Range: 2.25V (4.5V) to 6V (12V) less than 50ns, making them ideal for multiplexing and n Available in 16-Lead SSOP Package portable applications. U APPLICATIO S The LT6553 is manufactured on Linear Technologys proprietary low voltage complementary bipolar process n RGB Amplifiers and is available in the 16-lead SSOP package that fits in the n Coaxial Cable Drivers same PCB area as an SO-8 package. n LCD Projectors , LTC and LT are registered trademarks of Linear Technology Corporation.
