The LT

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 150

Ω 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.
