LMH6739 Very Wideband, Low Distortion Triple Video Buffer November 2004 LMH6739 Very Wideband, Low Distortion Triple Video Buffer General Description The LMH6739 is a very wideband, DC coupled monolithic programmable gain buffer 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 LMH6739 offers gains of −1, 1 and 2. At a gain of +2 the LMH6739 supports ultra high resolution video systems with a 400 MHz 2 VPP 3 dB Bandwidth. With 12-bit distortion level through 30 input referred noise, the MHz (RL = 100Ω), 2.3nV/ LMH6739 is the ideal driver or buffer for high speed flash A/D and D/A converters.
