Gain/ Diff. Phase (RL = 150Ω) 2mA shutdown current Description The LMH6739 is a very wideband, DC coupled monolithic selectable 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 MHz (RL = 100Ω), 2.3nV/ √Hz input referred noise, the LMH6739 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 LMH6739’s low input referred noise and low harmonic distortion make it an attractive solution. The LMH6739 is offered in a space saving SSOP package. Applications RGB video driver High resolution projectors Flash A/D driver D/A transimpedance buffer Wide dynamic range IF amp Radar/communication receivers DDS post-amps Wideband inverting summer Line driver

LMH6739MQ	VIP 10	0	13411	0	0	1245000	3	353272149
LMH6739MQX	VIP 10	0	13411	0	0	1245000	3	353272149

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
