DESCRIPTION

The LMH6739 is a very wideband, DC coupled

monolithic selectable gain buffer designed specifically

for ultra high resolution video systems as well as wide

dynamic range systems requiring exceptional signal

fidelity. Benefiting from current feedback architecture,

the LMH6739 offers gains of −1, 1 and 2. At a gain of +2 the LMH6739 supports ultra high resolution video

systems with a 400 MHz 2 VPP3 dB Bandwidth. With

12-bit distortion level through 30 MHz (RL = 100Ω),

2.3nV/√Hz input referred noise, the LMH6739 is the

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

converters. Wide dynamic range systems such as radar and communication receivers requiring a

wideband amplifier offering exceptional signal purity

will find the LMH6739 low input referred noise and

low harmonic distortion make it an attractive solution.

The LMH6739 is offered in a space saving SSOP

package.
