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 of-
fers 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 = 100), 2.3nV/
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 dis-
tortion make it an attractive solution. The LMH6739 is avail-
able in a space saving SSOP package.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications, see the Electrical Characteristics tables.
Note 2: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of
the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ> TA.
See Applications Section for information on temperature de-rating of this device. Min/Max ratings are based on product characterization and simulation. Individual
parameters are tested as noted.
Note 3: The maximum output current (IOUT) is determined by device power dissipation limitations. See the Power Dissipation section of the Application Section for
more details.
Note 4: Human body model: 1.5 kin series with 100 pF. Machine model: 0in series with 200 pF.
Note 5: Short circuit current should be limited in duration to no more than 10 seconds. See the Power Dissipation section of the Application Section for more details.
Note 6: Parameter 100% production tested at 25˚ C.
