These current feedback amplifiers feature gain flatness of 0.1 dB to 10 MHz while offering differential gain and phase error of 0.05% and 0.1°. This makes the AD8072 and AD8073 ideal for business and consumer video electronics. Both will operate from a single 5 V to 12 V power supply. The outputs of each amplifier swing to within 1.3 volts of either supply rail to accommodate video signals on a single 5 V supply. The high bandwidth of 100 MHz, 500 V/µs of slew rate, along with settling to 0.1% in 25 ns, make the AD8072 and AD8073 useful in many general purpose, high speed applications where a single 5 V or dual power supplies up to ± 6 V are needed. The AD8072 is available in 8-lead plastic DIP, SOIC, and µSOIC packages while the AD8073 is available in 14-lead plastic DIP and SOIC packages. Both operate over the commercial temperature range of 0°C to 70°C. Additionally, the AD8072ARM operates over the industrial temperature range of –40°C to +85°C. R EV.

In addition to being low cost, these amplifiers deliver solid video performance into a 150 Ω load while consuming only 3.5 mA per amplifier of supply current. Furthermore, the AD8073 is three amplifiers in a single 14-lead narrow-body SOIC package. This makes it ideal for applications where small size is essential. Each amplifier’s inputs and output are accessible providing added gain setting flexibility.

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2 Specification is for device in free air: 8-Lead Plastic Package: θJA = 90°C/W 8-Lead SOIC Package: θJA = 140°C/W 8-Lead µSOIC Package: θJA = 214°C/W 14-Lead Plastic Package: θJA = 75°C/W 14-Lead SOIC Package: θJA = 120°C/W The maximum power that can be safely dissipated by the AD8072 and AD8073 is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150°C. Exceeding this limit temporarily may cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Exceeding a junction temperature of 175° C for an extended period can result in device failure. While the AD8072 and AD8073 are internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature (150°C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves shown in Figures 2 and 3. 2.0 8-LEAD MINI-DIP PACKAGE MAXIMUM POWER DISSIPATION – W TJ = 150 C 1.5 8-LEAD SOIC PACKAGE 1.0 ORDERING GUIDE Model *AD8072ARM *AD8072ARM-REEL *AD8072ARM-REEL7 AD8072JN AD8072JR AD8072JR-REEL AD8072JR-REEL7 AD8073JN AD8073JR AD8073JR-REEL AD8073JR-REEL7 *Brand Code: HLA 0.5 SOIC Temperature Range –40°C to +85°C –40°C to +85°C –40°C to +85°C 0°C to 70°C 0°C to 70°C 0°C to 70°C 0°C to 70°C 0°C to 70°C 0°C to 70°C 0°C to 70°C 0°C to 70°C Package Description 8-Lead µSOIC 13" Reel 8-Lead µSOIC 7" Reel 8-Lead µSOIC 8-Lead Plastic DIP 8-Lead SOIC 13" Reel 8-Lead SOIC 7" Reel 8-Lead SOIC 14-Lead Plastic DIP 14-Lead Narrow SOIC 13" Reel 14-Lead SOIC 7" Reel 14-Lead SOIC Package Option RM-8 RM-8 RM-8 N-8 SO-8 SO-8 SO-8 N-14 R-14 R-14 R-14 0 –50 –40 –30 –20 –10 0 10 20 30 40 50 60 AMBIENT TEMPERATURE – C 70 80 90 Figure 2.

D AD8072/AD8073 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. On the other hand, the bandwidth of a current feedback amplifier 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 kΩ. Figure 5 shows the frequency response of an AD8072/AD8073 at a gain of two with both feedback and gain resistors equal to 2 kΩ. Capacitive Load Drive VIN VOUT When an op amp output drives a capacitive load, extra phase shift due to the pole formed by the op amp’s output impedance and the capacitor can cause peaking or even oscillation. The top trace of Figure 6, RS = 0 Ω, shows the output of one of the amplifiers 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 Ω r esistor in series with it. In general, the resistor value will have to be experimentally determined, but 10 Ω to 50 Ω is a practical range of values to experiment with for capacitive loads of up to a few hundred pF. 1V 25ns Figure 4. Overload Recovery; VS = ± 5 V, VIN = 8 V p-p, RF = 1 kΩ, RL = 150 Ω, G = +2 Bandwidth vs. Feedback Resistor Value RS = 0Ω RS = 25Ω 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 feedback 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 Ω. For resistances below this value, the gain flatness will be affected and more significant lot-to-lot variations in device performance will be noticed. Figure 5 shows a plot of the frequency response of an AD8072/AD8073 at a gain of two with both feedback and gain resistors equal to 649 Ω. 6.1 6.0 5.9 5.8 0.1 dB DIV 5.7 VS = 5V AV = 2 RL = 150 VO = 0.2V p-p 3 1 dB DIV 7 6 CLOSED-LOOP GAIN – dB 50mV 20ns Figure 6.

D –9– AD8072/AD8073 Crosstalk Layout Considerations 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) The specified high speed performance of the AD8072 and AD8073 require careful attention to board layout and component 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 µF–10 µF) 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’s 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 inverting 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 Ω or 75 Ω and be properly terminated at each end.
