LMH6714/6720/6722 Wideband Video Op Amp; Single, Single with Shutdown and Quad
March 2003
General Description
The LMH6714/6720/6722 series combine National’s
™
VIP10
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
The LMH6714/6720/6722 series offer exceptional video performance with its 0.01% and 0.01˚ differential gain and
phase errors for NTSC and PAL video signals while driving a
back terminated 75Ω load. They also offer a flat gain response 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 applications. 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.
