Application Section
LMH6718 OPERATION
The LMH6718 is a current feedback buffer fabricated in an
advanced complementary bipolar process. The LMH6718
operates from a single 5V supply or dual
±
5V supplies.
Operating from a single 5V supply, the LMH6718 has the
following features:
Gains of
±
1, 1, and 2V/V are achievable without exter-
nal resistors
Provides 170mA of output current
Offers low 88/91dBc 2nd & 3rd harmonic distortion
Provides BW
>
110MHz
The LMH6718 performance is further enhanced in
±
5V sup-
ply applications as indicated in the
±
5V Electrical Charac-
teristics
table and the
±
5V Typical Performance
plots.
LMH6718 DESIGN INFORMATION
CLOSED LOOP GAIN SELECTION
The LMH6718 is a current feedback op amp with R
= R
=
1k
on chip (in the package). Select from three closed loop
gains without using any external gain or feedback resistors.
Implement gains of +2, +1, and 1V/V by connecting pins 2
and 3 (or 5 and 6) as described in the chart below.

The gain accuracy of the LMH6718 is excellent and stable
over temperature change. The internal gain setting resistors,
R
and R
are poly silicon resistors. Although their absolute
values change with processing and temperature, their ratio
(R
F
/R
G
) remains constant. If an external resistor is used in
series with R
G
, gain accuracy over temperature will suffer.
SINGLE SUPPLY OPERATION (V
CC
= +5V, V
EE
= GND)
The specifications given in the
+5V Electrical Characteris-
tics
table for single supply operation are measured with a
common mode voltage (V
CM
) of 2.5V. V
CM
is the voltage
around which the inputs are applied and the output voltages
are specified.
Operating from a single +5V supply, the Common Mode
Voltage Range (CMVR) of the LMH6718 is typically +0.8V to
+4.2V. The typical output range with R
L
= 100
is +1.0V to
+4.0V.
For single supply DC coupled operation, keep input signal
levels above 0.8V DC, AC coupling and level shifting the
signal are recommended. The non-inverting and inverting
configurations for both input conditions are illustrated in the
following 2 sections.

the recommended configurations for input signals that re-
main above 0.8V DC.
