LT6552 3.3V Single Supply Video Difference Amplifier UFEATURESDESCRIPTIO ■ 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/ µ s Slew Rate configurations. A second set of inputs gives gain adjust- ■ –3dB Bandwidth = 75MHz, A ment and DC control to the differential amplifier. V = ± 2 ■ CMRR at 10MHz: >60dB On a single 3.3V supply, the input voltage range extends ■ Specified on 3.3V, 5V and ±5V Supplies from ground to 1.3V and the output swings from ground ■ High Output Drive: ±70mA to 2.9V while driving a 150Ω load. The LT6552 features ■ Power Shutdown to 300µA 75MHz – 3dB bandwidth, 600V/µs slew rate, and ±70mA ■ Operating Temperature Range: –40°C to 85°C output current making it ideal for driving cables directly. ■ 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 U supplies. The shutdown feature reduces power dissipa- APPLICATIO S tion to less than 1mW and allows multiple amplifiers to ■ Differential to Single-Ended Conversion drive the same cable. ■ Video Line Driver The LT6552 is available in the 8-lead SO package as well ■ Automotive Displays as a tiny, dual fine pitch leadless package (DFN). The ■ RGB Amplifiers device is specified over the commercial and industrial ■ Coaxial Cable Drivers temperature ranges. ■ Low Voltage High Speed Signal Processing , LTC and LT are registered trademarks of Linear Technology Corporation.
