Application Notes

LM7171 Performance Discussion

The LM7171 is a very high speed, voltage feedback ampli-

fier. It consumes only 6.5 mA supply current while providing

a unity-gain bandwidth of 200 MHz and a slew rate of 4100V/

µs. It also has other great features such as low differential

gain and phase and high output current.

LM7171 Circuit Operation

The class AB input stage in LM7171 is fully symmetrical and

has a similar slewing characteristic to the current feedback

amplifiers. In the LM7171 Simplified Schematic, Q1 through

Q4 form the equivalent of the current feedback input buffer,

The LM7171 is a true voltage feedback amplifier. Unlike cur-

rent feedback amplifiers (CFAs) with a low inverting input im-

pedance and a high non-inverting input impedance, both in-

puts of voltage feedback amplifiers (VFAs) have high

impedance nodes. The low impedance inverting input in

COMPONENT SELECTION AND FEEDBACK RESISTOR

LM7171 Circuit Operation (Continued)

It is important in high speed applications to keep all compo-

nent leads short. For discrete components, choose carbon

composition-type resistors and mica-type capacitors. Sur-

face mount components are preferred over discrete compo-

nents for minimum inductive effect.

ers the inverting input. The triple-buffered output stage iso-

lates the gain stage from the load to provide low output im-

pedance.

LM7171 Slew Rate Characteristic

Large values of feedback resistors can couple with parasitic

capacitance and cause undesirable effects such as ringing

or oscillation in high speed amplifiers. For LM7171, a feed-

back resistor of 510Ω gives optimal performance.

The slew rate of LM7171 is determined by the current avail-

able to charge and discharge an internal high impedance

node capacitor. This current is the differential input voltage

divided by the total degeneration resistor R_E. Therefore, the

slew rate is proportional to the input voltage level, and the

higher slew rates are achievable in the lower gain configura-

tions. A curve of slew rate versus input voltage level is pro-

vided in the “Typical Performance Characteristics”.

Compensation for Input

Capacitance

The combination of an amplifier’s input capacitance with the

gain setting resistors adds a pole that can cause peaking or

oscillation. To solve this problem, a feedback capacitor with

a value

When a very fast large signal pulse is applied to the input of

an amplifier, some overshoot or undershoot occurs. By plac-

ing an external resistor such as 1 kΩ in series with the input

of LM7171, the bandwidth is reduced to help lower the over-

shoot.

C_F(R_Gx C_IN)/R_F

can be used to cancel that pole. For LM7171, a feedback ca-

pacitor of 2 pF is recommended. Figure 1 illustrates the com-

pensation circuit.

Slew Rate Limitation

If the amplifier’s input signal has too large of an amplitude at

too high of a frequency, the amplifier is said to be slew rate

limited; this can cause ringing in time domain and peaking in

frequency domain at the output of the amplifier.

In the “Typical Performance Characteristics” section, there

are several curves of A_V+2 and A_V+4 versus input sig-

nal levels. For the A_V+4 curves, no peaking is present and

the LM7171 responds identically to the different input signal

levels of 30 mV, 100 mV and 300 mV.

DS012385-10

For the A_V

+2 curves, with slight peaking occurs. This

FIGURE 1. Compensating for Input Capacitance

peaking at high frequency ( 100 MHz) is caused by a large

input signal at high enough frequency that exceeds the am-

plifier’s slew rate. The peaking in frequency response does

not limit the pulse response in time domain, and the LM7171

is stable with noise gain of ≥+2.

Power Supply Bypassing

Bypassing the power supply is necessary to maintain low

power supply impedance across frequency. Both positive

and negative power supplies should be bypassed individu-

ally by placing 0.01 µF ceramic capacitors directly to power

supply pins and 2.2 µF tantalum capacitors close to the

power supply pins.

Layout Consideration

PRINTED CIRCUIT BOARDS AND HIGH SPEED OP

AMPS

There are many things to consider when designing PC

boards for high speed op amps. Without proper caution, it is

very easy to have excessive ringing, oscillation and other de-

graded AC performance in high speed circuits. As a rule, the

signal traces should be short and wide to provide low induc-

tance and low impedance paths. Any unused board space

needs to be grounded to reduce stray signal pickup. Critical

components should also be grounded at a common point to

eliminate voltage drop. Sockets add capacitance to the

board and can affect high frequency performance. It is better

to solder the amplifier directly into the PC board without us-

ing any socket.

USING PROBES

DS012385-11

Active (FET) probes are ideal for taking high frequency mea-

surements because they have wide bandwidth, high input

impedance and low input capacitance. However, the probe

ground leads provide a long ground loop that will produce er-

rors in measurement. Instead, the probes can be grounded

directly by removing the ground leads and probe jackets and

using scope probe jacks.

FIGURE 2. Power Supply Bypassing

Termination

In high frequency applications, reflections occur if signals

are not properly terminated. Figure 3 shows a properly termi-

nated signal while Figure 4 shows an improperly terminated

signal.

Power Dissipation

The maximum power allowed to dissipate in a device is de-

fined as:

DS012385-18

FIGURE 4. Improperly Terminated Signal

P_D(T_J(max)− T_A)/θ_JA

To minimize reflection, coaxial cable with matching charac-

teristic impedance to the signal source should be used. The

other end of the cable should be terminated with the same

value terminator or resistor. For the commonly used cables,

RG59 has 75Ω characteristic impedance, and RG58 has

50Ω characteristic impedance.

For example, for the LM7171 in a SO-8 package, the maxi-

Driving Capacitive Loads

Amplifiers driving capacitive loads can oscillate or have ring-

ing at the output. To eliminate oscillation or reduce ringing,

an isolation resistor can be placed as shown below in Figure

5 The combination of the isolation resistor and the load ca-

pacitor forms a pole to increase stability by adding more

phase margin to the overall system. The desired perfor-

mance depends on the value of the isolation resistor; the big-

ger the isolation resistor, the more damped the pulse re-

sponse becomes. For LM7171, a 50Ω isolation resistor is

Thermal resistance, θ_JA, depends on parameters such as

die size, package size and package material. The smaller

the die size and package, the higher θ_JAbecomes. The 8-pin

DIP package has a lower thermal resistance (108˚C/W) than

that of 8-pin SO (172˚C/W). Therefore, for higher dissipation

capability, use an 8-pin DIP package.

The total power dissipated in a device can be calculated as:

P_DP_Q+ P_L

recommended for initial evaluation. Figure

6 shows the

P_Qis the quiescent power dissipated in a device with no load

connected at the output. P_Lis the power dissipated in the de-

vice with a load connected at the output; it is not the power

dissipated by the load.

Furthermore,

P_Q

supply current x total supply voltage with no load

output current (voltage difference between
