The LMH6739 is a very wideband, DC coupled monolithic selectablegain buffer designed specifically for ultra high resolutionvideo systems as well as wide dynamic range systemsrequiring exceptional signal fidelity. Benefiting from National'scurrent feedback architecture, the LMH6739 offers gains of−1, 1 and 2. At a gain of +2 the LMH6739 supports ultra highresolution video systems with a 400 MHz 2 VPP3 dB Bandwidth. With 12-bit distortion level through 30 MHz(RL = 100Ω), 2.3nV/√Hz input referred noise, the LMH6739is the ideal driver or buffer for high speed flash A/D and D/Aconverters. Wide dynamic range systems such as radar andcommunication receivers requiring a wideband amplifier offeringexceptional signal purity will find the LMH6739’s lowinput referred noise and low harmonic distortion make it anattractive solution. The LMH6739 is offered in a space savingSSOP package.
