LMH6738
Very Wideband, Low Distortion Triple Op Amp
General Description
The LMH6738 is a very wideband, DC coupled monolithic
operational amplifier designed specifically for ultra high reso-
lution video systems as well as wide dynamic range systems
requiring exceptional signal fidelity. Benefiting from Nation-
al’s current feedback architecture, the LMH6738 offers a
gain range of ±1 to ±10 while providing stable, operation
without external compensation, even at unity gain. At a gain
of +2 the LMH6738 supports ultra high resolution video
systems with a 400 MHz 2 VPP –3 dB Bandwidth. With 12-bit
distortion levels through 30 MHz (RL = 100), 2.3 nV/
Hz input referred noise, the LMH6738 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 LMH6738’s low input referred noise
and low harmonic distortion make it an attractive solution.

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.
