LM7171 Performance Discussion
The LM7171 is a very high speed, voltage feedback ampli-
fier. It consumes only 6.5 mA supply current while providing
a unity-gain bandwidth of 200 MHz and a slew rate of 4100V/
μs. It also has other great features such as low differential
gain and phase and high output current.
The LM7171 is a true voltage feedback amplifier. Unlike cur-
rent feedback amplifiers (CFAs) with a low inverting input im-
pedance and a high non-inverting input impedance, both in-
puts of voltage feedback amplifiers (VFAs) have high
impedance nodes. The low impedance inverting input in
CFAs and a feedback capacitor create an additional pole
that will lead to instability. As a result, CFAs cannot be used
in traditional op amp circuits such as photodiode amplifiers,
I-to-V converters and integrators where a feedback capacitor
is required.
LM7171 Circuit Operation
The class AB input stage in LM7171 is fully symmetrical and
has a similar slewing characteristic to the current feedback
amplifiers. In the LM7171 Simplified Schematic, Q1 through
Q4 form the equivalent of the current feedback input buffer,
R

the equivalent of the feedback resistor, and stage A buff-
