LMH6723/LMH6724/LMH6725
Single/Dual/Quad 370 MHz 1 mA Current Feedback Op
Amp
General Description
The LMH6723/LMH6724/LMH6725 provides a 260 MHz
small signal bandwidth at a gain of +2 V/V and a 600 V/s
slew rate while consuming only 1 mA from
5V supplies.
The LMH6723/LMH6724/LMH6725 supports video applica-
tions with its 0.03% and 0.11 differential gain and phase
errors for NTSC and PAL video signals while driving a back
terminated 75
load. The LMH6723/LMH6724/LMH6725
also offers a flat gain response of 0.1 dB to 100 MHz.
Additionally, the LMH6723/LMH6724/LMH6725 can deliver
110 mA of linear output current. This level of performance, as
well as a wide supply range of 4.5 to 12V, makes the
LMH6723/LMH6724/LMH6725 an ideal op amp for a variety
of
portable
applications.
The
LMH6723/LMH6724/
LMH6725's small packages (SOIC & SOT23), low power
requirement and high performance, allow the LMH6723/
LMH6724/LMH6725 to serve a wide variety of portable ap-
plications.
The LMH6723/LMH6724/LMH6725 is manufactured in Na-
tional's VIP
TM
10 complimentary bipolar process.

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 T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where T
J
>
T
A
.
See Applications Section for information on temperature derating of this device. Min/Max ratings are based on product characterization and simulation. Individual
parameters are tested as noted.

Note 3: The maximum continuous output current (I
OUT
) is determined by device power dissipation limitations. See the Power Dissipation section of the Application
Section for more details.
