CIRCUIT 3 |
The EL5164, EL5165, and EL5364 are current-feedback operational amplifiers that offer a wide -3dB bandwidth of 600MHz and a low supply current of 3.5mA per amplifier. The EL5164, EL5165, and EL5364 work with supply voltages ranging from a single 5V to 10V and they are also capable of swinging to within 1V of either supply on the output. Because of their current-feedback topology, the EL5164, EL5165, and EL5364 do not have the normal gain- bandwidth product associated with voltage-feedback operational amplifiers. Instead, their -3dB bandwidth remains relatively constant as closed-loop gain increases. This combination of high bandwidth and low power, together with aggressive pricing makes the EL5164, EL5165, and EL5364 ideal choices for many low- power/high-bandwidth applications such as portable, handheld, or battery-powered equipment. For varying bandwidth needs, consider the EL5166 and EL5167 with 1.4GHz bandwidth and an 8.5mA supply current, or the EL5162 and EL5163 with 500MHz bandwidth and a 1.5mA supply current. Versions include single, dual, and triple amp configurations with 5 Ld SOT-23, 16 Ld QSOP, and 8 Ld SOIC or 16 Ld SOIC outlines.
As with any high frequency device, good printed circuit board layout is necessary for optimum performance. Low impedance ground plane construction is essential. Surface mount components are recommended, but if leaded components are used, lead lengths should be as short as possible. The power supply pins must be well bypassed to reduce the risk of oscillation. The combination of a 4.7µF tantalum capacitor in parallel with a 0.01µF capacitor has been shown to work well when placed at each supply pin.
For good AC performance, parasitic capacitance should be kept to a minimum, especially at the inverting input. (See the “Capacitance at the Inverting Input” on page 10). Even when ground plane construction is used, it should be removed from the area near the inverting input to minimize any stray capacitance at that node. Carbon or Metal-Film resistors are acceptable with the Metal-Film resistors giving slightly less peaking and bandwidth because of additional series inductance. Use of sockets, particularly for the SO package, should be avoided if possible. Sockets add parasitic inductance and capacitance which results in additional peaking and overshoot.
The EL5164 and EL5364 amplifiers can be disabled, placing their outputs in a high impedance state. When disabled, the amplifiers supply current reduces to <25µA per amplifier. An amplifier disables when its CE pin is pulled up to within 1V of the positive supply. Similarly, the amplifier is enabled by floating or pulling its CE pin to at least 3V below the positive supply. For a
±5V supply, this means that an amplifier enables when its CE is 2V or less, and disables when CE is above 4V. Although the logic levels are not standard TTL, this choice of logic voltages allows the amplifiers to be enabled by tying CE to ground, even in 5V single supply applications. The CE pin can be driven from CMOS outputs.
When the amplifier is disabled, if the positive input is driven beyond ±2V with respect to the negative input, the device can become active and output the signal. An input diode clamp
network D1 and D2, as shown in Figure 23, can be used to keep the device disabled while a large input signal is present.

peaking can be easily modified by varying the value of the feedback resistor.
Because the EL5164, EL5165, and EL5364 are current-feedback amplifiers, their gain-bandwidth product is not a constant for different closed-loop gains. This feature actually allows the EL5164, EL5165, and EL5364 to maintain about the same -3dB bandwidth. As gain is increased, bandwidth decreases slightly while stability increases. Since the loop stability is improving with higher closed-loop gains, it becomes possible to reduce the value
of RF below the specified 412 and still retain stability, resulting in only a slight loss of bandwidth with increased closed-loop gain.
The EL5164, EL5165, and EL5364 are designed to operate with supply voltages having a span of 5V to 10V. In practical terms, this means that they will operate on dual supplies ranging from
±2.5V to ±5V. With a single-supply, the EL5164, EL5165, and EL5364 will operate from 5V to 10V.
As supply voltages continue to decrease, it becomes necessary to provide input and output voltage ranges that can get as close as possible to the supply voltages. The EL5164, EL5165, and EL5364 have an input range which extends to within 2V of either

Any manufacturer’s high-speed voltage- or current-feedback amplifier can be affected by stray capacitance at the inverting input. For inverting gains, this parasitic capacitance has little effect because the inverting input is a virtual ground, but for non- inverting gains, this capacitance (in conjunction with the feedback and gain resistors) creates a pole in the feedback path of the amplifier. This pole, if low enough in frequency, has the same destabilizing effect as a zero in the forward open-loop response. The use of large-value feedback and gain resistors exacerbates the problem by further lowering the pole frequency (increasing the possibility of oscillation.)
The EL5164, EL5165, and EL5364 are optimized for a 510 feedback resistor at AV = +1. With the high bandwidth of these amplifiers, these resistor values might cause stability problems
when combined with parasitic capacitance, thus ground plane is not recommended around the inverting input pin of the amplifier.
The EL5164, EL5165, and EL5364 have been designed and specified for a gain of +2 with RF approximately 412. This value of feedback resistor gives 450MHz of -3dB bandwidth at AV = 2 with 1dB of peaking. With AV = -2, an RF of 300 gives 275MHz of bandwidth with 1dB of peaking. Since the EL5164, EL5165,
and EL5364 are current-feedback amplifiers, it is also possible to change the value of RF to get more bandwidth. As seen in the curves of “Frequency Response for Various RF”, bandwidth and
supply output range is larger because of the increased negative swing due to the external pull-down resistor to ground.
For good video performance, an amplifier must maintain the same output impedance and the same frequency response as DC levels are changed at the output. This is especially difficult when driving a standard video load of 150, because of the change in output current with DC level. Previously, good differential gain could only be achieved by running high idle currents through the output transistors (to reduce variations in output impedance.) These currents were typically comparable to the entire 3.5mA supply current of each EL5164, EL5165, and EL5364 amplifier. Special circuitry has been incorporated in the EL5164, EL5165, and EL5364 to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.01% and 0.01°, while driving 150 at a gain of 2.
Video performance has also been measured with a 500 load at a gain of +1. Under these conditions, the EL5164, EL5165, and EL5364 have dG and dP specifications of 0.01% and 0.01°, respectively.
In spite of their low 3.5mA of supply current, the EL5164, EL5165, and EL5364 are capable of providing a minimum of ±100mA of output current. With a minimum of ±100mA of output drive, the EL5164, EL5165, and EL5364 are capable of driving 50 loads to both rails, making it an excellent choice for driving isolation transformers in telecommunications applications.
When used as a cable driver, double termination is always recommended for reflection-free performance. For those

applications, the back-termination series resistor will decouple the EL5164, EL5165, and EL5364 from the cable and allow extensive capacitive drive. However, other applications may have high capacitive loads without a back-termination resistor. In
these applications, a small resistor (usually between 5 and

50) can be placed in series with the output to eliminate most peaking. The gain resistor (RG) can then be chosen to make up for any gain loss which may be created by this additional resistor
at the output. In many cases it is also possible to simply increase the value of the feedback resistor (RF) to reduce the peaking.

With the high output drive capability of the EL5164, EL5165, and EL5364, it is possible to exceed the +125°C Absolute Maximum junction temperature under certain very high load current conditions. Generally speaking when RL falls below about 25, it
