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 V_PP –3 dB
Bandwidth. With 12-bit distortion levels through 30
MHz (R_L = 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.
