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. MAXIMUM POWER DISSIPATION The maximum safe power dissipation in the packages is limited by the associated rise in junction temperature (T J ) on the die. The plastic encapsulating the die will locally reach the junction temperature. At approximately 5 C, which is the glass transition temperature, the plastic will change its properties. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the AD87/ AD88. Exceeding a junction temperature of 75 C for an extended period of time can result in changes in the silicon devices, potentially causing failure. The still-air thermal properties of the package and PCB (θ JA ), ambient temperature (T A ), and the total power dissipated in the package (P D ) determine the junction temperature of the die. The junction temperature can be calculated as follows: TJ = TA + ( PD θja) The power dissipated in the package (P D ) is the sum of the quiescent power dissipation and the power dissipated in the package due to the load drive for all outputs. The quiescent power is the voltage between the supply pins (V S ) times the quiescent current (I S ). Assuming the load (R L ) is referenced to midsupply, the total drive power is V S / I OUT, some of which is dissipated in the package and some in the load (V OUT I OUT ). The difference between the total drive power and the load power is the drive power dissipated in the package. P D = quiescent power + (total drive power load power): VS V PD = ( VS IS)+ R OUT L OUT V R L RMS output voltages should be considered. If R L is referenced to V S, as in single-supply operation, then the total drive power is V S I OUT. If the rms signal levels are indeterminate, then consider the worst case, when V OUT = V S /4 for R L to midsupply: VS 4 PD = ( VS IS)+ RL In single-supply operation, with R L referenced to V S, worst case is VS VOUT = Airflow will increase heat dissipation, effectively reducing θ JA. Also, more metal directly in contact with the package leads from metal traces, through holes, ground, and power planes will reduce the θ JA. Care must be taken to minimize parasitic capacitances at the input leads of high speed op amps as discussed in the board layout section. Figure shows the maximum safe power dissipation in the package versus ambient temperature for the SOIC-8 (5 C/W), MSOP (5 C/W), and SC7 ( C/W) packages on a JEDEC standard 4-layer board. θ JA values are approximations.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4 V readily accumulate on the human body and test equipment and can discharge without detection. Although the features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. 4

14 THEORY OF OPERATION The AD87 (single) and AD88 (dual) are current feedback amplifiers optimized for low distortion performance. A simplified conceptual diagram of the AD87 is shown in Figure. It closely resembles a classic current feedback amplifier comprised of a complementary emitter-follower input stage, a pair of signal mirrors, and a diamond output stage. However, in the case of the, several modifications have been made to greatly improve the distortion performance over that of a classic current feedback topology. USING THE Supply Decoupling for Low Distortion Decoupling for low distortion performance requires careful consideration. The commonly adopted practice of returning the high frequency supply decoupling capacitors to physically separate (and possibly distant) grounds can lead to degraded even-order harmonic performance. This situation is shown in Figure 4 using the AD87 as an example. Note that for a sinusoidal input, each decoupling capacitor returns to its ground a quasi-rectified current carrying high even-order harmonics.

High Frequency Capacitors Returned R F to Physically Separate Grounds (Not Recommended) R G The decoupling scheme shown in Figure 5 is preferable. Here, the two high frequency decoupling capacitors are first tied together at a common node, and are then returned to the Figure. Simplified Schematic of AD87 The signal mirrors have been replaced with low distortion, high precision mirrors. They are shown as M and M in Figure. Their primary function from a distortion standpoint is to greatly reduce the effect of highly nonlinear distortion caused by capacitances C J and C J. These capacitors represent the collector-to-base capacitances of the mirrors output devices. A voltage imbalance arises across the output stage, as measured from the high impedance node HiZ to the output node Out. This imbalance is a result of delivering high output currents and is the primary cause of output distortion. Circuitry is included to sense this output voltage imbalance and generate a compensating current I DO. When injected into the circuit, I DO reduces the distortion that would be generated at the output stage. Similarly, the nonlinear voltage imbalance across the input stage (measured from the noninverting to the inverting input) is sensed, and a current I DI is injected to compensate for input-generated distortion. The design and layout are strictly top-to-bottom symmetric in order to minimize the presence of even-order harmonics. V S. F F + ground plane through a single connection. By first adding the two currents flowing through each high frequency decoupling capacitor, one is ensuring that the current returned into the ground plane is only at the fundamental frequency.

High Frequency Capacitors Returned to Ground at a Single Point (Recommended) Whenever physical layout considerations prevent the decoupling scheme shown in Figure 5, the user can connect one of the high frequency decoupling capacitors directly across the supplies and connect the other high frequency decoupling capacitor to ground. This is shown in Figure 6. 4

High Frequency Capacitors Connected across the Supplies (Recommended) Layout Considerations The standard noninverting configuration with recommended power supply bypassing is shown in Figure 6. The. µf high frequency decoupling capacitors should be X7R or NPO chip components. Connect C from the +V S pin to the V S pin. Connect C from the +V S pin to signal ground. The length of the high frequency bypass capacitor leads is critical. Parasitic inductance due to long leads will work against the low impedance created by the bypass capacitor. The ground for the load impedance should be at the same physical location as the bypass capacitor grounds. For the larger value capacitors, which are intended to be effective at lower frequencies, the current return path distance is less critical. Output Capacitance To a lesser extent, parasitic capacitances on the output can cause peaking of the frequency response. There are two methods to effectively minimize its effect:. Put a small value resistor in series with the output to isolate the load capacitance from the amplifier s output stage. (See TPC 7.). Increase the phase margin by (a) increasing the amplifier s gain or (b) adding a pole by placing a capacitor in parallel with the feedback resistor. Input-to-Output Coupling To minimize capacitive coupling, the input and output signal traces should not be parallel. This helps reduce unwanted positive feedback. External Components and Stability The AD87 and AD88 are current feedback amplifiers and, to a first order, the feedback resistor determines the bandwidth and stability. The gain, load impedance, supply voltage, and input impedances also have an effect. TPC 6 shows the effect of changing R F on bandwidth and peaking for a gain of +. Increasing R F will reduce peaking but also reduce the bandwidth. TPC shows that for a given R F, increasing the gain will also reduce peaking and bandwidth. Table I shows the recommended R F and R G values that optimize bandwidth with minimal peaking. Table I. Recommended Component Values Gain R F (Ω) R G (Ω) R S (Ω) LAYOUT AND GROUNDING CONSIDERATIONS Grounding NA A ground plane layer is important in densely packed PC boards to minimize parasitic inductances. However, an understanding of where the current flows in a circuit is critical to implementing effective high speed circuit design. The length of the current path is directly proportional to the magnitude of parasitic inductances and thus the high frequency impedance of the path. High and 5. A comparison between TPCs and 5 also demonstrates The load resistor will also affect bandwidth as shown in TPCs speed currents in an inductive ground return will create an the effect of gain and supply voltage. unwanted voltage noise. Broad ground plane areas will reduce When driving loads with a capacitive component, stability is the parasitic inductance. improved by using a series snub resistor R SNUB at the output. Input Capacitance The frequency and pulse responses for various capacitive loads Along with bypassing and ground, high speed amplifiers can be are illustrated in TPCs 7 and 4, respectively. sensitive to parasitic capacitance between the inputs and ground. For noninverting configurations, a resistor in series with the input, Even pf or pf of capacitance will reduce the input impedance at high frequencies, in turn increasing the amplifier s gain, in TPC. For larger noninverting gains, the effect of a series R S, is needed to optimize stability for Gain = +, as illustrated causing peaking of the frequency response or even oscillations resistor is reduced. if severe enough. It is recommended that the external passive components that are connected to the input pins be placed as close as possible to the inputs to avoid parasitic capacitance. The ground and power planes must be kept at a distance of at least.5 mm from the input pins on all layers of the board. 5
