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
