The LM6171 is a high speed, unity-gain stable voltage feedback amplifier. It consumes only 2.5 mA supply current while providing a gain-bandwidth product of 100 MHz and a slew rate of 3600V/μs. It also has other great features such as low differential gain and phase and high output current. The LM6171 is a good choice in high speed circuits. The LM6171 is a true voltage feedback amplifier. Unlike current feedback amplifiers (CFAs) with a low inverting input impedance and a high non-inverting input impedance, both inputs of voltage feedback amplifiers (VFAs) have high impedance nodes. The low impedance inverting input in CFAs will couple with feedback capacitor and cause oscillation.

As a result, CFAs cannot be used in traditional op amp circuits such as photodiode amplifiers, I-to-V converters and integrators.

指标解释：

1．DISTRIBUTION

2. The input bias currents are junction leakage currents which approximately double for every 10oC increase in the junction temperature Tamb. Due to limited production test time, the input bias current measured is correlated to junction temperature.In a normal operation the junction temperature rises above the ambient temperature as a result of internal power dissipation ,Ptot-Tamb =Tamb+Rth(j-a) x Ptot where Rth(j-a)is the thermal resistance from junction to ambient. Use of a heatsink is recommended f input currents are to be kept to a minimum.3 Supply voltage rejection is measured for both supply magnitudes increasing or decreasing simultaneously, in accordance with common practise.

4. Settling time is defined here, for a unity gain inverter connection using

2k resistors for the LF155, LF156 series. It is the time required for the error voltage (the voltage at the inverting input pin on the amplifier) to settle to within 0.01% of its final value from the time a 10V step input is applied to the inverter. For the LF157 series AV = -5, the feedback resistor from output to input is 2k and the output step is 10V.

应用技巧：

1．There are many things to consider when designing PC boards for high speed op amps. Without proper caution, it is very easy and frustrating to have excessive ringing, oscillation and other degraded AC performance in high speed circuits. As a rule, the signal traces should be short and wide to provide low inductance 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 frequency performance.It is better to solder the amplifier directly into the PCboard without using any socket.

2．COMPONENTS SELECTION AND FEEDBACK RESISTOR

It is important in high speed applications to keep all component leads short because wires are inductive at high frequency.

For discrete components, choose carbon

composition-type resistors and mica-type

capacitors. Surface mount components are

preferred over discrete components for minimum

inductive effect. Large values of feedback resistors can couple with parasitic capacitance and cause undesirable effects such as ringing or oscillation in high speed amplifiers. For LM6171, a feedback resistor of 510Ω gives optimal performance. 3．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 C F > (R G x C IN)/R F can be used to cancel that pole. For

LM6171, a feedback capacitor of 2 pF is recommended. Figure 1illustrates the compensation circuit.

4．Driving Capacitive Loads

Amplifiers driving capacitive loads can oscillate or have

ringing at the output. To eliminate oscillation or reduce

ringing,an isolation resistor can be placed as shown

below in Figure5. The combination of the isolation

resistor and the load capacitor forms a pole to increase

stablility by adding more phase margin to the overall

system. The desired performance depends on the value

of the isolation resistor; the bigger the isolation resistor,

the more damped the pulse response becomes. For

LM6171, a 50Ω isolation resistor is

recommended for initial evaluation. Figure 6 shows the

LM6171 driving a 200 pF load with the 50Ω isolation resistor.

5．A common error for the first-time CFB user is the creation of a unity gain buffer amplifier by shorting the output directly to the inverting input. A CFB amplifier in this configuration will oscillate and is not recommended. The THS300x, like all CFB amplifiers, must have a feedback resistor for stable operation. Additionally, placing capacitors directly from the output to the inverting input is not recommended. This is because, at high frequencies, a capacitor has a very low impedance. This results in an unstable amplifier and should not be considered when using a current-feedback amplifier. Because of this, integrators and simple low-pass filters, which are easily implemented on a VFB amplifier, have to be designed slightly differently. If filtering is required, simply place an RC-filter at the noninverting terminal of the operational-amplifier (see Figure Figure 57. Single-Pole Low-Pass Filter）

If a multiple-pole filter is required, the use of a Sallen-Key filter can work very well with CFB amplifiers. This is because the filtering elements are not in the negative feedback loop and stability is not compromised. Because of their high slew-rates and high bandwidths, CFB amplifiers can create very accurate signals and help minimize distortion. An example is shown in Figure 58.

Figure 58. 2-Pole Low-Pass Sallen-Key Filter

There are two simple ways to create an integrator with a CFB amplifier. The first, shown in Figure 59, adds a resistor in series with the capacitor. This is acceptable because at high frequencies, the resistor is dominant and the feedback impedance never drops below the resistor value. The second, shown in Figure 60, uses positive feedback to create the integration. Caution is advised because oscillations can occur due to the positive feedback.
