3.3V Single Supply

Video Difference Amplifier

FEATURES

DESCRIPTIO

The LT^®6552 is a video difference amplifier optimized for

low voltage single supply operation. This versatile ampli-

fier features uncommitted high input impedance (+) and

(–) inputs and can be used in differential or single-ended

configurations. A second set of inputs gives gain adjust-

ment and DC control to the differential amplifier.

■

Differential or Single-Ended Gain Block

■

Wide Supply Range 3V to 12.6V

■

Output Swings Rail-to-Rail

■

Input Common Mode Range Includes Ground

■

600V/µs Slew Rate

■

–3dB Bandwidth = 75MHz, A_V= ±2

■

CMRR at 10MHz: >60dB

On a single 3.3V supply, the input voltage range extends

from ground to 1.3V and the output swings from ground

to 2.9V while driving a 150Ω load. The LT6552 features

75MHz – 3dB bandwidth, 600V/µs slew rate, and ±70mA

output current making it ideal for driving cables directly.

The LT6552 maintains its performance for supplies from

3V to 12.6V and is fully specified at 3.3V, 5V and ±5V

supplies. The shutdown feature reduces power dissipa-

tion to less than 1mW and allows multiple amplifiers to

drive the same cable.
