3.3V Single Supply
Video Difference Amplifier
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.
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.
The LT6552 is available in the 8-lead SO package as well
as a tiny, dual fine pitch leadless package (DFN). The
device is specified over the commercial and industrial
temperature ranges.
