DESCRIPTION
The LMH6714/LMH6720/LMH6722 series combine
Texas Instruments' VIP10 high speed complementary
bipolar process with Texas Instruments' 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/LMH6720/LMH6722 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/LMH6720/LMH6722's small packages
(SOIC, SOT-23 and WSON), low power requirement,
low noise and distortion allow the
LMH6714/LMH6720/LMH6722 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.
