FEATURES
DESCRIPTION
The LMH™6703 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

architecture, the LMH6703 offers a practical gain
range of ±1 to ±10 while providing stable operation
without external compensation, even at unity gain. At
a gain of +2 the LMH6703 supports ultra high
resolution video systems with a 750 MHz 2 VPP −3 dB
Bandwidth. With 12-bit distortion levels through 10
MHz (RL = 100Ω), and a 2.3nV/√Hz input referred
noise, the LMH6703 is the ideal driver or buffer for
high speed flash A/D and D/A converters. Wide
