LMH6718 Dual, High Output, Programmable Gain Buffer
January 2003
LMH6718
Dual, High Output, Programmable Gain Buffer
General Description
The LMH6718 is a dual, low cost high speed (130MHz)
buffer which features user programmable gains of +2, +1,
and -1V/V. The LMH6718 also has a new output stage that
delivers high output drive current (200mA), but consumes
minimal quiescent supply current (2.6mA/Amp) from a
±
5V
supply. Its current feedback architecture, fabricated in an
advanced complementary bipolar process, maintains consis-
tent performance over a wide range of signal levels, and has
a linear phase response up to one half of the -3dB frequency.
The LMH6718 offers 0.1dB gain flatness to 30MHz and
differential gain and phase errors of .04% and .03˚. These
features are ideal for professional and consumer video ap-
plications.
The LMH6718 offers superior dynamic performance with a
130MHz small-signal bandwidth, 600V/µs slew rate and
4.2ns rise/fall times (2V
STEP
). The combination of low quies-
cent current, high output current drive, and high speed per-
formance makes the LMH6718 well suited for many battery
powered personal communication/computing systems. The
ability to drive low impedance, high capacitive loads, makes
the LMH6718 ideal for single ended cable applications. It
also drives low impedance loads with minimum distortion.
The LMH6718 will drive a 100Ω load with only −84/−84dBc
second/third harmonic distortion (A
V
= +2, V
OUT
= 2V
PP
, f =
1MHz). It is also optimized for driving high currents into
single-ended transformers and coils. When driving the input
of high resolution A/D converters, the LMH6718 provides
excellent -88/-98dBc second/third harmonic distortion (A
V
=
+2, V
OUT
= 2V
PP
, f = 1MHz, R
L
= 1kΩ) and fast settling time.
The LMH6718 is fabricated using National’s VIP10
com-
plimentary 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 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 current is determined by device power dissipation limitations. See the Power Dissipation section of the Application Division for more details.
