APPLICATION NOTES:
PERFORMANCE DISCUSSION: The LM7171 is a very high speed, voltage feedback amplifier. It
consumes only 6.5mA supply current while providing a gain-bandwidth product of 170MHz
(Minimum) and a slew rate of 2000V/uS (Minumum). 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 current feedback amplifiers (CFAs)
with a low inverting input impedance and a high non-inverting input impedance, both inputs
of voltage feedback amplifiers (VFA's) have high impedance nodes. The low impedance
inverting input in CFA's and a feedback capacitor create an additional pole that will lead
to instability. As a result, CFA's cannot be used in traditional op amp circuits such as
photodiode amplifiers, I-to-V converters and integrators, where a feedback capacitor is
required.
