DESCRIPTION
The LMH6734 is a high speed 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 TI's current feedback architecture, the
LMH6734 offers gains of 1, +1 and +2. At a gain of
+2 the LMH6734 supports ultra high resolution video
systems with a 560 MHz 2 VPP3 dB bandwidth. With
this large signal bandwidth and 2.1 nV/Hz of input
referred noise, the LMH6734 is ideal for driving
component video over CAT5 cable up to 200 ft
without frequency and gain equalization. The
LMH6734 is offered in a space saving 16-Pin SSOP
package.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 ensured. For ensured specifications, see the Electrical
Characteristics tables.

specifications.

(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 ensured. For ensured specifications, see the Electrical
Characteristics tables.
(2) The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(MAX) - TA) / θJA. All numbers apply for packages soldered directly onto a PC Board.

(1) 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 Application Information 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.
(2) Limits are 100% production tested at 25C. Limits over the operating temperature range are specified through correlation using Statistical
Quality Control (SQC) methods.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not specified on shipped
production material.
