3 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
fidelity. Benefitting from current feedback
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 V_PP, −3-
dB Bandwidth. With 12-bit distortion levels through 10
MHz (R_L = 100 Ω), and a 2.3-nV/√Hz input referred
noise, the LMH6703 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
LMH6703 low input referred noise and low harmonic
distortion an attractive solution.
