LMH6714/6720/6722
Wideband Video Op Amp; Single, Single with Shutdown
and Quad
General Description
The
LMH6714/6720/6722
series
combine
National’s
VIP10
high speed complementary bipolar process with
National’s current feedback topology to produce a very high
speed op amp. These amplifiers provide a 400MHz small
signal bandwidth at a gain of +2V/V and a 1800V/μs slew
rate while consuming only 5.6mA from
±
5V supplies.
The LMH6714/6720/6722 series offer exceptional video per-
formance with its 0.01% and 0.01 differential gain and
phase errors for NTSC and PAL video signals while driving a
back terminated 75
load. They also offer a flat gain re-
sponse of 0.1dB to 120MHz. Additionally, they can deliver
70mA continuous output current. This level of performance
makes them an ideal op amp for broadcast quality video
systems.
The
LMH6714/6720/6722’s
small
packages
(SOIC
&
SOT23), low power requirement, low noise and distortion
allow the LMH6714/6720/6722 to serve portable RF applica-
tions. The high impedance state during shutdown makes the
LMH6720 suitable for use in multiplexing multiple high speed
signals onto a shared transmission line. The LMH6720 is
also ideal for portable applications where current draw can
be reduced with the shutdown function.
