FEATURES

DESCRIPTION

2

•

750 MHz

−3 dB small signal bandwidth

The LMH6739 is a very wideband, DC coupled

monolithic selectable gain buffer designed specifically

•

for ultra high resolution video systems as well as wide

•

2.3 nV/

√Hz input noise voltage

dynamic range systems requiring exceptional signal

fidelity. Benefiting from current feedback architecture,

•

3300 V/

μs slew rate

the LMH6739 offers gains of

−1, 1 and 2. At a gain of

•

32 mA supply current (10.6 mA per op amp)

+2 the LMH6739 supports ultra high resolution video

•

90 mA linear output current

•

2.3nV/

√Hz input referred noise, the LMH6739 is the

•

2mA shutdown current

ideal driver or buffer for high speed flash A/D and D/A

converters. Wide dynamic range systems such as

APPLICATIONS

radar

and

communication

receivers

requiring

a

wideband amplifier offering exceptional signal purity

•

RGB video driver

will find the LMH6739 low input referred noise and

•

High resolution projectors

low harmonic distortion make it an attractive solution.

•

Flash A/D driver

The LMH6739 is offered in a space saving SSOP

•

D/A transimpedance buffer

package.

•

Wide dynamic range IF amp

•

Radar/communication receivers

•

DDS post-amps

•

Wideband inverting summer

•

Line driver
