R
f
while maintaining the same closed-loop gain—the amplifier bandwidth decreases. Accordingly, larger
feedback resistors can be used to slow down the LM6181 (see −3 dB bandwidth vs R
f
typical curves) and reduce
overshoot in the time domain response. Conversely, smaller feedback resistance values than 820Ω can be used
to compensate for the reduction of bandwidth at high closed loop gains, due to 2nd order effects. For example
Figure 82 illustrates reducing R
f
to 500Ω to establish the desired small signal response in an amplifier configured
for a closed loop gain of 25.
