LT6552 3.3V Single Supply Video Difference Amplifier FEATURES DESCRIPTIO n The LT 6552 is a video difference amplifier optimized for Differential or Single-Ended Gain Block n low voltage single supply operation. This versatile ampli- Wide Supply Range 3V to 12.6V n fier features uncommitted high input impedance (+) and Output Swings Rail-to-Rail n () inputs and can be used in differential or single-ended Input Common Mode Range Includes Ground n configurations. A second set of inputs gives gain adjust- 600V/s Slew Rate n ment and DC control to the differential amplifier. 3dB Bandwidth = 75MHz, A = 2 V n CMRR at 10MHz: >60dB On a single 3.3V supply, the input voltage range extends n Specified on 3.3V, 5V and 5V Supplies from ground to 1.3V and the output swings from ground n High Output Drive: 70mA to 2.9V while driving a 150 load. The LT6552 features n Power Shutdown to 300A 75MHz 3dB bandwidth, 600V/s slew rate, and 70mA n Operating Temperature Range: 40C to 85C output current making it ideal for driving cables directly. n Available in 8-Lead SO and The LT6552 maintains its performance for supplies from Tiny 3mm x 3mm x 0.8mm DFN Packages 3V to 12.6V and is fully specified at 3.3V, 5V and 5V supplies. The shutdown feature reduces power dissipa- U APPLICATIO S tion to less than 1mW and allows multiple amplifiers to drive the same cable. n Differential to Single-Ended Conversion n Video Line Driver The LT6552 is available in the 8-lead SO package as well n Automotive Displays as a tiny, dual fine pitch leadless package (DFN). The n RGB Amplifiers device is specified over the commercial and industrial n Coaxial Cable Drivers temperature ranges. n Low Voltage High Speed Signal Processing , LTC and LT are registered trademarks of Linear Technology Corporation.
