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 National’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’s low input referred noise
and low harmonic distortion make it an attractive solution.
