LT6552

3.3V Single Supply

Video Difference Amplifier

FEATURES DESCRIPTIO

Differential or Single-Ended Gain Block The LT®6552 is a video difference amplifier optimized for Wide Supply Range 3V to 12.6V low voltage single supply operation. This versatile ampli- Output Swings Rail-to-Rail fier features uncommitted high input impedance (+) and Input Common Mode Range Includes Ground (–) inputs and can be used in differential or single-ended 600V/µs Slew Rate configurations. A second set of inputs gives gain adjust- –3d B Bandwidth = 75MHz, AV = ±2 ment and DC control to the differential amplifier.
