rev. d ad8072/ad8073 C9C applications overdrive recovery overdrive of an amplifier occurs when the output and/or input range are exceeded. the amplifier must recover from this overdrive condition and resume normal operation. as shown in figure 4, the ad8072 and ad8073 recover within 75 ns from positive overdrive and 30 ns from negative overdrive. 25ns 1v v in v out figure 4. overload recovery; v s = 5 v, v in = 8 v p-p, r f = 1 k ? , r l = 150 ? , g = +2 bandwidth vs. feedback resistor value the closed-loop frequency response of a current feedback amplifier is a function of the feedback resistor. a smaller feedback resistor will produce a wider bandwidth response. however, if the feed- back resistance becomes too small, the gain flatness can be affected. as a practical consideration, the minimum value of feedback resistance for the ad8072/ad8073 was found to be 649 ? . for resistances below this value, the gain flatness will be affected and more significant lot-to-lot variations in device per- formance will be noticed. figure 5 shows a plot of the frequency response of an ad 8072/ad8073 at a gain of two with both feed- back and gain resistors equal to 649 ? . frequency mhz 6.1 gain flatness db 6.0 0.1 500 1 10 100 5.9 5.8 5.4 5.7 5.6 5.5 r f = 2k r f = 649 1 db div 0.1 db div 6 7 5 4 3 2 1 0 v s = 5v a v = 2 r l = 150 v o = 0.2v p-p closed-loop gain db figure 5. frequency response vs. r f on the other hand, the bandwidth of a current feedback ampli- fier can be decreased by increasing the feedback resistance. this can sometimes be useful where it is desired to reduce the noise bandwidth of a system. as a practical matter, the maximum value of feedback resistor was found to be 2 k ? . figure 5 shows the frequency response of an ad8072/ad8073 at a gain of two with both feedback and gain resistors equal to 2 k ? . capacitive load drive when an op amp output drives a capacitive load, extra phase shift due to the pole formed by the op amp? output impedance and the capacitor can cause peaking or even oscillation. the top trace of figure 6, r s = 0 ? , shows the output of one of the amplifi ers of the ad8072/ad8073 when driving a 50 pf capacitor as shown in the schematic of figure 7. the amount of peaking can be significantly reduced by adding a resistor in series with the capacitor. the lower trace of figure 6 shows the same capacitor being driven with a 25 ? resistor in series with it. in general, the resistor value will have to be experimentally determined, but 10 ? to 50 ? is a practical range of values to experiment with for capacitive loads of up to a few hundred pf. 20ns 50mv r s = 0 ? r s = 25 ? figure 6. capacitive low drive 1k 1k 50 v in = 100mv p-p r l 1k c l 50pf r s figure 7. capacitive load drive circuit
rev. d ad8072/ad8073 C10C crosstalk crosstalk between internal amplifiers may vary depending on which amplifier is being driven and how many amplifiers are being driven. this variation typically stems from pin location on the package and the internal layout of the ic itself. table i illustrates the typical crosstalk results for a combination of conditions. table i. ad8073jr crosstalk table (db) receive amplifier ad8073jr 123 1 x ?0 ?6 drive 2 ?0 x ?0 amplifier 3 ?4 ?0 x all hostile ?3 ?5 ?4 conditions v s = 5 v r f = 1 k ? , r l = 150 ? a v = 2 v out = 2 v p-p on drive amplifier layout considerations the specified high speed performance of the ad8072 and ad8073 require careful attention to board layout and compo- nent selection. proper rf design techniques and low parasitic component selection are mandatory. the pcb should have a ground plane covering all unused portions of the component side of the board to provide a low impedance ground path. the ground plane should be removed from the area near the input pins to reduce stray capacitance. chip capacitors should be used for supply bypassing. one end of the capacitor should be connected to the ground plane and the other within 1/8 inches of each power pin. an additional large (4.7 f?0 f) tantalum electrolytic capacitor should be connected in parallel, but not necessarily as close to the supply pins, to provide current for fast large-signal changes at the device? output. the feedback resistor should be located close to the inverting input pin in order to keep the stray capacitance at this node to a minimum. capacitance variations of less than 1 pf at the invert- ing input will affect high speed performance. stripline design techniques should be used for long signal traces (greater than approximately 1 inch). these should be designed with a characteristic impedance of 50 ? or 75 ? and be properly terminated at each end.
