4 / 15 page 4 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 TRANSIENT CHARACTERISTICS AV = +2 (Note 3), Unless Otherwise Specified Rise and Fall Times (VOUT =0.5VP-P, Note 3) AV = +2 B 25 - 0.8 - - 0.9 - ns AV = +6 B 25 - 2.9 - - 4 - ns Overshoot (VOUT =0.5VP-P, VIN tRISE = 1ns, Notes 3, 6) AV = -1, +OS B 25 - 7 - - 3 - % AV = -1, -OS B 25 - 8 - - 13 - % AV = +2, +OS B 25 - 5 - - 7 - % AV = +2, -OS B 25 - 10 - - 11 - % AV = +6, +OS B 25 - 2 - - 2 - % AV = +6, -OS B 25 - 2 - - 2 - % Slew Rate (VOUT =5VP-P, Notes 3, 5) AV = -1, +SR B 25 - 2500 - - 2500 - V/ µs AV = -1, -SR B 25 - 1900 - - 1900 - V/ µs AV = +2, +SR B 25 - 1700 - - 1600 - V/ µs AV = +2, -SR B 25 - 1700 - - 1400 - V/ µs AV = +6, +SR B 25 - 1500 - - 1000 - V/ µs AV = +6, -SR B 25 - 1100 - - 1000 - V/ µs Settling Time (VOUT = +2V to 0V Step, Note 5) To 0.1% B 25 - 23 - - 23 - ns To 0.05% B 25 - 30 - - 30 - ns To 0.025% B 25 - 37 - - 40 - ns Overdrive Recovery Time VIN = ±2V B 25 - 8.5 - - 8.5 - ns VIDEO CHARACTERISTICS AV = +2 (Note 3), Unless Otherwise Specified Differential Gain (f = 3.58MHz) RL = 150Ω B 25 - 0.02 - - 0.03 - % RL =75Ω B 25 - 0.03 - - 0.06 - % Differential Phase (f = 3.58MHz) RL = 150Ω B 25 - 0.03 - - 0.03 - Degrees RL =75Ω B 25 - 0.06 - - 0.06 - Degrees POWER SUPPLY CHARACTERISTICS Power Supply Range C 25 ±4.5 - ±5.5 ±4.5 - ±5.5 V Power Supply Current (Note 5) A 25 - 5.8 6.1 - 5.8 6.1 mA/Op Amp A Full - 5.9 6.3 - 5.9 6.3 mA/Op Amp 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.
