DESCRIPTION

The LMH6738 is a very wideband, DC coupled

monolithic operational amplifier designed specifically

for ultra high resolution video systems as well as wide

dynamic range systems requiring exceptional signal

fidelity. Benefiting from TI’s current feedback

architecture, the LMH6738 offers a gain range of ±1 to ±10 while providing stable, operation without

external compensation, even at unity gain. At a gain

of +2 the LMH6738 supports ultra high resolution

video systems with a 400 MHz 2 VPP –3 dB

Bandwidth. With 12-bit distortion levels through 30

MHz (RL = 100Ω), 2.3 nV/Hz input referred noise, the

LMH6738 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 LMH6738 low input referred

noise and low harmonic distortion make it an

attractive solution.
