NOTES:
3. The optimum feedback resistor depends on closed loop gain and package type. See the “Optimum Feedback Resistor” table in the Application
Information section for details.
4. Test Level: A. Production Tested; B. Typical or Guaranteed Limit Based on Characterization; C. Design Typical for Information Only.
5. See Typical Performance Curves for more information.
6. Undershoot dominates for output signal swings below GND (e.g., 2VP-P), yielding a higher overshoot limit compared to the VOUT = 0V to 2V
condition. See the “Application Information” section for details.
Application Information
Performance Differences Between Packages
The amplifiers comprising the HFA1405 are high frequency
current feedback amplifiers. As such, they are sensitive to
feedback capacitance which destabilizes the op amp and
causes overshoot and peaking. Unfortunately, the standard
quad op amp pinout places the amplifier’s output next to its
inverting input, thus making the package capacitance an
unavoidable parasitic feedback capacitor. The larger
parasitic capacitance of the PDIP requires an inherently
more stable amplifier, which yields a PDIP device with lower
performance than the SOIC device - see Electrical
Specification tables for details.
Because of these performance differences, designers
should evaluate and breadboard with the same package
style to be used in production.
Note that the “Typical Performance Curves” section has
separate pulse and frequency response graphs for each
