LMH6715
Dual Wideband Video Op Amp
General Description
The LMH6715 combines National’s VIP10™ high speed
complementary bipolar process with National’s current feed-
back topology to produce a very high speed dual op amp.
The LMH6715 provides 400MHz small signal bandwidth at a
gain of +2V/V and 1300V/µs slew rate while consuming only
5.8mA per amplifier from ±5V supplies.
The LMH6715 offers exceptional video performance with its
0.02% and 0.02˚ differential gain and phase errors for NTSC
and PAL video signals while driving up to four back termi-
nated 75Ω loads. The LMH6715 also offers a flat gain re-
sponse of 0.1dB to 100MHz and very low channel-to-
channel crosstalk of −70dB at 10MHz. Additionally, each
amplifier can deliver 70mA of output current. This level of
performance makes the LMH6715 an ideal dual op amp for
high density, broadcast quality video systems.
The LMH6715’s two very well matched amplifiers support a
number of applications such as differential line drivers and
receivers. In addition, the LMH6715 is well suited for Sallen
Key active filters in applications such as anti-aliasing filters
for high speed A/D converters. Its small 8-pin SOIC package,
low power requirement, low noise and distortion allow the
LMH6715 to serve portable RF applications such as IQ
channels.
