LMH6682, LMH6683 SNOSA43A–MAY2004–REVISEDAPRIL2013 www.ti.com APPLICATIONS SECTION LARGE SIGNAL BEHAVIOR Amplifying high frequency signals with large amplitudes (as in video applications) has some special aspects to look after. The bandwidth of the Op Amp for large amplitudes is less than the small signal bandwidth because of slew rate limitations. While amplifying pulse shaped signals the slew rate properties of the OpAmp become more importantathigheramplituderanges.DuetotheinternalstructureofanOpAmptheoutputcanonlychangewith a limited voltage difference per time unit (dV/dt). This can be explained as follows: To keep it simple, assume that an Op Amp consists of two parts; the input stage and the output stage. In order to stabilize the Op Amp, the output stage has a compensation capacitor in its feedback path. This Miller C integrates the current from the input stage and determines the pulse response of the Op Amp. The input stage must charge/discharge the feedbackcapacitor,ascanbeseeninFigure51. Figure51. When a voltage transient is applied to the non inverting input of the Op Amp, the current from the input stage will charge the capacitor and the output voltage will slope up. The overall feedback will subtract the gradually increasing output voltage from the input voltage. The decreasing differential input voltage is converted into a currentbytheinputstage(Gm). I*Δt=C*ΔV (1) ΔV/Δt=I/C (2) I=ΔV*Gm (3) whereI=current t=time C=capacitance V=voltage Gm=transconductance SlewrateΔV/Δt=volt/second In most amplifier designs the current I is limited for high differential voltages (Gm becomes zero). The slew rate willthanbelimitedaswell: ΔV/Δt=Imax/C (4) The LMH6682/83 has a different setup of the input stage. It has the property to deliver more current to the output stage when the input voltage is higher (class AB input). The current into the Miller capacitor exhibits an exponential character, while this current in other Op Amp designs reaches a saturation level at high input levels: (seeFigure52) 16 SubmitDocumentationFeedback Copyright©2004–2013,TexasInstrumentsIncorporated ProductFolderLinks:LMH6682 LMH6683

HANDLING VIDEO SIGNALS Whenhandlingvideosignals,twoaspectsareveryimportantespeciallywhencascadingamplifiersinaNTSC-or PAL video system. A composite video signal consists of both amplitude and phase information. The amplitude represents saturation while phase determines color (color burst is 3.59MHz for NTSC and 4.58MHz for PAL systems). In this case it is not only important to have an accurate amplification of the amplitude but also it is important not to add a varying phase shift to the video signals. It is a known phenomena that at different dc levels over a certain load the phase of the amplified signal will vary a little bit. In a video chain many amplifiers will be cascaded and all errors will be added together. For this reason, it is necessary to have strict requirements for the variation in gain and phase in conjunction to different dc levels. As can be seen in the tables the number forthedifferentialgainfortheLMH6682/83isonly0.01%andforthedifferentialphaseitisonly0.08°atasupply voltage of ±5V. Note that the phase is very dependent of the load resistance, mainly because of the dc current delivered by the parts output stage into the load.

LMH6682, LMH6683 SNOSA43A–MAY2004–REVISEDAPRIL2013 www.ti.com OUTPUT PHASE REVERSAL Thisisaproblemwithsomeoperationalamplifiers.Thiseffectiscausedbyphasereversalintheinputstagedue to saturation of one or more of the transistors when the inputs exceed the normal expected range of voltages. Some applications, such as servo control loops among others, are sensitive to this kind of behavior and would need special safeguards to ensure proper functioning. The LMH6682/6683 is immune to output phase reversal with input overload. With inputs exceeded, the LMH6682/6683 output will stay at the clamped voltage from the supply rail. Exceeding the input supply voltages beyond the Absolute Maximum Ratings of the device could howeverdamageorotherwiseadverselyeffectthereliabilityorlifeofthedevice. DRIVING CAPACITIVE LOADS The LMH6682/6683 can drive moderate values of capacitance by utilizing a series isolation resistor between the output and the capacitive load. Capacitive load tolerance will improve with higher closed loop gain values. Applications such as ADC buffers, among others, present complex and varying capacitive loads to the Op Amp; best value for this isolation resistance is often found by experimentation and actual trial and error for each application. DISTORTION Applications with demanding distortion performance requirements are best served with the device operating in the inverting mode. The reason for this is that in the inverting configuration, the input common mode voltage does not vary with the signal and there is no subsequent ill effects due to this shift in operating point and the possibility of additional non-linearity. Moreover, under low closed loop gain settings (most suited to low distortion), the non-inverting configuration is at a further disadvantage of having to contend with the input common voltage range. There is also a strong relationship between output loading and distortion performance (i.e. 2kΩ vs. 100Ω distortion improves by about 15dB @1MHz) especially at the lower frequency end where the distortion tends to be lower. At higher frequency, this dependence diminishes greatly such that this difference is only about 5dB at 10MHz. But, in general, lighter output load leads to reduced HD3 term and thus improves THD.(SeeHarmonicDistortionplots,Figures19through23). PRINTED CIRCUIT BOARD LAYOUT AND COMPONENT VALUES SELECTION Generally it is a good idea to keep in mind that for a good high frequency design both the active parts and the passive ones are suitable for the purpose you are using them for. Amplifying frequencies of several hundreds of MHz is possible while using standard resistors but it makes life much easier when using surface mount ones. These resistors (and capacitors) are smaller and therefore parasitics have lower values and will have less influence on the properties of the amplifier. Another important issue is the PCB, which is no longer a simple carrier for all the parts and a medium to interconnect them. The board becomes a real part itself, adding its own high frequency properties to the overall performance of the circuit. It's good practice to have at least one ground plane on a PCB giving a low impedance path for all decouplings and other ground connections. Care should be taken especially that on board transmission lines have the same impedance as the cables they are connected to (i.e. 50Ω for most applications and 75Ω in case of video and cable TV applications). These transmission lines usually require much wider traces on a standard double sided PCB than needed for a 'normal' connection. Another important issue is that inputs and outputs must not 'see' each other or are routed together over the PCB at a small distance. Furthermore it is important that components are placed as flat as possible on the surface of the PCB. For higher frequencies a long lead can act as a coil, a capacitor or an antenna. A pair of leads can even form a transformer. Careful design of the PCB avoids oscillations or other unwanted behavior. When working with really high frequencies, the only components which can be used will be the surface mount ones (for moreinformationseeOA-15SNOA367). As an example of how important the component values are for the behavior of your circuit, look at the following case: On a board with good high frequency layout, an amplifier is placed. For the two (equal) resistors in the feedbackpath,5differentvaluesareusedtosetthegainto+2.Theresistorsvaryfrom200Ω to3kΩ. 18 SubmitDocumentationFeedback Copyright©2004–2013,TexasInstrumentsIncorporated ProductFolderLinks:LMH6682 LMH6683

In Figure 54 it can be seen that there's more peaking with higher resistor values, which can lead to oscillations and bad pulse responses. On the other hand the low resistor values will contribute to higher overall power consumption.
