Optimum Feedback Resistor
Although a current feedback amplifier’s bandwidth
dependency on closed loop gain isn’t as severe as that of a
voltage feedback amplifier, there can be an appreciable
decrease in bandwidth at higher gains. This decrease may
be minimized by taking advantage of the current feedback
amplifier’s unique relationship between bandwidth and RF.
All current feedback amplifiers require a feedback resistor,
even for unity gain applications, and RF, in conjunction with
the internal compensation capacitor, sets the dominant pole
of the frequency response. Thus, the amplifier’s bandwidth is
inversely proportional to RF. The HFA1135 design is
optimized for a 250
RF at a gain of +2. Decreasing RF
decreases stability, resulting in excessive peaking and
overshoot (Note: Capacitive feedback will cause the same

NOTES:
2. Test Level: A. Production Tested; B. Typical or Guaranteed Limit Based on Characterization; C. Design Typical for Information Only.
3. The optimum feedback resistor for the HFA1135 at AV = +1 is 1.5k. The Production Tested parameters are tested with RF = 510 because
the HFA1135 shares test hardware with the HFA1105 amplifier.
4. Undershoot dominates for output signal swings below GND (e.g., 0.5VP-P), yielding a higher overshoot limit compared to the VOUT = 0V to 0.5V
condition. See the “Application Information” section for details.
5. See Typical Performance Curves for more information.
6. Slew rates are asymmetrical if the output swings below GND (e.g., a bipolar signal). Positive unipolar output signals have symmetric positive and
negative slew rates comparable to the +SR specification. See the “Application Information” section, and the pulse response graphs for details.
