SOIC-14 (R) and TSSOP-14 (RU) GENERAL DESCRIPTION The AD8029 (single), AD8030 (dual), and AD8040 (quad) are rail-to-rail input and output high speed amplifiers with a quiescent current of only 1.3 mA per amplifier. Despite their low power consumption, the amplifiers provide excellent performance with 125 MHz small signal bandwidth and 60 V/s slew rate. Analog Devices, Inc., proprietary XFCB process enables high speed and high performance on low power. systems where component density requires lower power dissipation. The AD8040W is an automotive grade version, qualified for automotive applications. The AD8029/AD8030 are the only low power, rail-to-rail input and output high speed amplifiers available in SOT23 and SC70 micro packages. The amplifiers are rated over the extended industrial temperature range, -40C to +125C. This family of amplifiers exhibits true single-supply operation with rail-to-rail input and output performance for supply voltages ranging from 2.7 V to 12 V. The input voltage range extends 200 mV beyond each rail without phase reversal. The dynamic range of the output extends to within 40 mV of each rail. The versatility of the AD8029/AD8030/AD8040 allows the user to operate the amplifiers on a wide range of supplies while consuming less than 6.5 mW of power. These features extend the operation time in applications ranging from battery-powered systems with large bandwidth requirements to high speed Rev. B INPUT 4.5 4.0 OUTPUT 3.5 VOLTAGE (V) The AD8029/AD8030/AD8040 provide excellent signal quality with minimal power dissipation. At G = +1, SFDR is -72 dBc at 1 MHz and settling time to 0.1% is only 80 ns. Low distortion and fast settling performance make these amplifiers suitable drivers for single-supply analog-to-digital converters. 5.0 3.0 2.5 2.0 1.5 1.0 G = +1 0.5 VS = +5V RL = 1k TIED TO MIDSUPPLY 0 TIME (s) 1s/DIV 03679-A-010 Figure 5.

If RL is referenced to VS-, as in single-supply operation, then the total drive power is VS x IOUT. Table 4. AD8029/AD8030/AD8040 Stress Ratings Rating 12.6 V See Figure 6 VS 0.5 V 1.8 V -65C to +125C -40C to +125C 300C If the rms signal levels are indeterminate, consider the worst case, when VOUT = VS/4 for RL to midsupply: PD = (VS x I S ) + RL Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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 AD8029/AD8030/ AD8040 package is limited by the associated rise in junction temperature (TJ) on the die. The plastic encapsulating the die locally reaches the junction temperature. At approximately 150C, which is the glass transition temperature, the plastic changes 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 AD8029/AD8030/AD8040. Exceeding a junction temperature of 175C for an extended period can result in changes in silicon devices, potentially causing failure. Airflow increases heat dissipation, effectively reducing JA. Also, more metal directly in contact with the package leads from metal traces, through holes, ground, and power planes reduce the JA. Care must be taken to minimize parasitic capacitances at the input leads of high speed op amps, as discussed in the PCB Layout section. Figure 6 shows the maximum safe power dissipation in the package versus the ambient temperature for the SOIC-8 (125C/W), SOT23-8 (160C/W), SOIC-14 (90C/W), TSSOP-14 (120C/W), and SC70-6 (208C/W) packages on a JEDEC standard 4-layer board. JA values are approximations. 2.5 The still-air thermal properties of the package and PCB (JA), ambient temperature (TA), and the total power dissipated in the package (PD) determine the junction temperature of the die. The junction temperature can be calculated as 2.0 SOIC-14 1.5 TSSOP-14 SOIC-8 1.0 0.5 SOT-23-8 SC70-6 0 -40 -30 -20 -10 0 10 20 30 40 50 60 70 80 90 100 110 120 AMBIENT TEMPERATURE (C) TJ = TA + (PD x JA) 03679-A-018 150C Figure 6. Maximum Power Dissipation The power dissipated in the package (PD) 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 (VS) times the quiescent current (IS). Assuming the load (RL) is referenced to midsupply, the total drive power is VS/2 x IOUT, some of which is dissipated in the package and some in the load (VOUT x IOUT). The difference between the total drive power and the load power is the drive power dissipated in the package. Output Short Circuit Shorting the output to ground or drawing excessive current from the AD8029/AD8030/AD8040 could cause catastrophic failure. ESD CAUTION PD = Quiescent Power + (Total Drive Power - Load Power) V V PD = (VS x I S ) + S x OUT RL 2 (VS /4 )2 In single-supply operation with RL referenced to VS-, worst case is VOUT = VS/2.

Simplified Schematic OUTPUT STAGE The AD8029 (single), AD8030 (dual), and AD8040 (quad) are rail-to-rail input and output amplifiers fabricated using Analog Devices' XFCB process. The XFCB process enables the AD8029/ AD8030/AD8040 to operate on 2.7 V to 12 V supplies with a 120 MHz bandwidth and a 60 V/s slew rate. A simplified sche-matic of the AD8029/AD8030/AD8040 is shown in Figure 50. The currents derived from the PNP and NPN input differential pairs are injected into the current mirrors MBOT and MTOP, thus establishing a common-mode signal voltage at the input of the output buffer. INPUT STAGE 1. It buffers and applies the desired signal voltage to the output devices, Q10 and Q11. 2. It senses the common-mode current level in the output devices. 3. It regulates the output common-mode current by establishing a common-mode feedback loop. For input common-mode voltages less than a set threshold (1.2 V below VCC), the resistor degenerated PNP differential pair (comprising Q1 toQ4) carries the entire ITAIL current, allowing the input voltage to go 200 mV below -VS. Conversely, input common-mode voltages exceeding the same threshold cause ITAIL to be routed away from the PNP differential pair and into the NPN differential pair through transistor Q9. Under this condition, the input common-mode voltage is allowed to rise 200 mV above +VS while still maintaining linear amplifier behavior. The transition between these two modes of operation leads to a sudden, temporary shift in input stage transconductance, gm, and dc parameters (such as the input offset voltage VOS), which in turn adversely affect the distortion performance. The SPD block shortens the duration of this transition, thus improving the distortion performance. As shown in Figure 50, the input differential pair is protected by a pair of two series diodes, connected in anti-parallel, which clamp the differential input voltage to approximately 1.5 V. The output buffer performs three functions: The output devices Q10 and Q11 work in a common-emitter configuration, and are Miller-compensated by internal capacitors, CMT and CMB. The output voltage compliance is set by the output devices' collector resistance RC (about 25 ), and by the required load current IL. For instance, a light equivalent load (5 k) allows the output voltage to swing to within 40 mV of either rail, while heavier loads cause this figure to deteriorate as RC x IL. Rev. B | Page 16 of 24 Data Sheet AD8029/AD8030/AD8040 APPLICATIONS WIDEBAND OPERATION For example, if using the values shown in Table 5 for a gain of 2, with resistor values of 2.5 k, the effective load at the output is 1.67 k. For inverting configurations, only the feedback resistor RF is in parallel with the output load. If the load is greater than that specified in the data sheet, the amplifier can introduce nonlinearities in its open-loop response, which increases distortion. Figure 53 and Figure 54 illustrate effective output loading and distortion performance. Increasing the resistance of the feedback network can reduce the current consumption, but has other implications.

Table 5 shows the effects of output loading and performance. When operating at unity gain, the effective load at the amplifier output is the resistance (RL) being driven by the amplifier. For gains other than 1, in noninverting configurations, the feedback network represents an additional current load at the amplifier output. The feedback network (RF + RG) is in parallel with RL, which lowers the effective resistance at the output of the amplifier. The lower effective resistance causes the amplifier to supply more current at the output. Lower values of feedback resistance increase the current draw, thus increasing the amplifier's power dissipation. HARMONIC DISTORTION (dBc) Figure 52. Wideband Inverting Gain Configuration Rev.

This can cause peaking and ringing in the amplifier's response if the RC time constant is too low. Figure 55 illustrates this effect. Peaking can be reduced by adding a small capacitor (1 pF-4 pF) across the feedback resistor. The best way to find the optimal value of capacitor is to empirically try it in your circuit. Another factor of higher resistance values is the impact it has on noise performance. Higher resistor values generate more noise. Each application is unique and therefore a balance must be reached between distortion, peaking, and noise performance. Table 5 outlines the trade-offs that different loads have on distortion, peaking, and noise performance. In gains of 1, 2, and 10, equivalent loads of 1 k, 2 k, and 5 k are shown. With increasing load resistance, the distortion and -3 dB bandwidth improve, while the noise and peaking degrade slightly.

Particular care must be exercised to minimize lead lengths of the bypass capacitors. Excess lead inductance can influence the frequency response and even cause high frequency oscillations. Using a multilayer board with an internal ground plane can help reduce ground noise and enable a more compact layout. Power supply pins are actually inputs to the op amp. Care must be taken to provide the op amp with a clean, low noise dc voltage source. To achieve the shortest possible trace length at the inverting input, the feedback resistor, RF, should be located the shortest distance from the output pin to the input pin. The return node of the resistor RG should be situated as close as possible to the return node of the negative supply bypass capacitor. On multilayer boards, all layers beneath the op amp should be cleared of metal to avoid creating parasitic capacitive elements. This is especially true at the summing junction, i.e., the inverting input, -IN. Extra capacitance at the summing junction can cause increased peaking in the frequency response and lower phase margin. Grounding To minimize parasitic inductances and ground loops in high speed, densely populated boards, a ground plane layer is critical. Understanding where the current flows in a circuit is critical in the implementation of high speed circuit design. The length of the current path is directly proportional to the magnitude of the parasitic inductances and thus the high frequency impedance of the path. Fast current changes in an inductive ground return will create unwanted noise and ringing. The length of the high frequency bypass capacitor pads and traces is critical. A parasitic inductance in the bypass grounding works against the low impedance created by the bypass capacitor. Because load currents flow from supplies as well as from ground, the load should be placed at the same physical location as the bypass capacitor ground. For large values of capacitors, which are intended to be effective at lower frequencies, the current return path length is less critical. Power supply bypassing is employed to provide a low impedance path to ground for noise and undesired signals at all frequencies. This cannot be achieved with a single capacitor type; but with a variety of capacitors in parallel the bandwidth of power supply bypassing can be greatly extended. The bypass capacitors have two functions: 1. Provide a low impedance path for noise and undesired signals from the supply pins to ground. 2. Provide local stored charge for fast switching conditions and minimize the voltage drop at the supply pins during transients. This is typically achieved with large electrolytic capacitors. Good quality ceramic chip capacitors should be used and always kept as close as possible to the amplifier package. A parallel combination of a 0.1 F ceramic and a 10 F electrolytic covers a wide range of rejection for unwanted noise. The 10 F capacitor is less critical for high frequency bypassing and, in most cases, one per supply line is sufficient. The values of capacitors are circuit-dependant and should be determined by the system's requirements.
