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 VPP, −3-dB Bandwidth. With 12-bit distortion levels through 10 MHz (RL = 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.
