1GHz Current Feedback Amplifier
Applications Information
Product Description
The EL5191C is a current-feedback operational amplifier that offers a wide -3dB bandwidth of 1GHz and a low supply current of 9mA per amplifier. The EL5191C works 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 currentfeedback topology, the EL5191C does not have the normal gain-bandwidth product associated with voltagefeedback operational amplifiers. Instead, its -3dB bandwidth to remain relatively constant as closed-loop gain is increased. This combination of high bandwidth and low power, together with aggressive pricing make the EL5191C the ideal choice for many low-power/highbandwidth applications such as portable, handheld, or battery-powered equipment. For varying bandwidth needs, consider the EL5192C with 600MHz on a 6mA supply current or the EL5193C with 300MHz on a 4mA supply current. Versions include single, dual, and triple amp packages with 5-pin SOT23, 16-pin QSOP, and 8-pin or 16-pin SO outlines. particularly for the SO package, should be avoided if possible. Sockets add parasitic inductance and capacitance which will result in additional peaking and overshoot.
Capacitance at the Inverting Input
Any manufacturer's high-speed voltage- or currentfeedback 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 openloop 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 EL5191C has been optimized with a 250 feedback resistor. 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.
Power Supply Bypassing and Printed Circuit Board Layout
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 4.7F tantalum capacitor in parallel with a 0.01F 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 section) 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,

Feedback Resistor Values
The EL5191C has been designed and specified at a gain of +2 with RF approximately 250. This value of feedback resistor gives 600MHz of -3dB bandwidth at AV=2 with about 2dB of peaking. With AV=-2, that same RF gives 450MHz of bandwidth with 0.6dB of peaking. Since the EL5191C is a current-feedback amplifier, it is also possible to change the value of RF to get more bandwidth. As seen in the curve of Frequency Response for Various RF and RG, bandwidth and peaking can be easily modified by varying the value of the feedback resistor. Because the EL5191C is a current-feedback amplifier, its gain-bandwidth product is not a constant for different closed-loop gains. This feature actually allows the EL5191C to maintain about the same -3dB bandwidth. As gain is increased, bandwidth decreases slightly while
EL5191C

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 250 and still retain stability, resulting in only a slight loss of bandwidth with increased closed-loop gain. Video performance has also been measured with a 500 load at a gain of +1. Under these conditions, the EL5191C has dG and dP specifications of 0.02% and 0.02, respectively.
Output Drive Capability
In spite of its low 9mA of supply current, the EL5191C is capable of providing a minimum of 95mA of output current. With a minimum of 95mA of output drive, the EL5191C is capable of driving 50 loads to both rails, making it an excellent choice for driving isolation transformers in telecommunications applications.
Supply Voltage Range and Single-Supply Operation
The EL5191C has been designed to operate with supply voltages having a span of greater than 5V and less than 10V. In practical terms, this means that the EL5191C will operate on dual supplies ranging from 2.5V to 5V. With single-supply, the EL5191C 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 EL5191C has an input range which extends to within 2V of either supply. So, for example, on 5V supplies, the EL5191C has an input range which spans 3V. The output range of the EL5191C is also quite large, extending to within 1V of the supply rail. On a 5V supply, the output is therefore capable of swinging from -4V to +4V. Single-supply output range is larger because of the increased negative swing due to the external pull-down resistor to ground.
Driving Cables and Capacitive Loads
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 EL5191C 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 series 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.
Video Performance
For good video performance, an amplifier is required to 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 9mA supply current of each EL5191C amplifier. Special circuitry has been incorporated in the EL5191C to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.035% and 0.04, while driving 150 at a gain of 2.
Current Limiting
The EL5191C has no internal current-limiting circuitry. If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power dissipation, potentially resulting in the destruction of the device.
Power Dissipation
With the high output drive capability of the EL5191C, it is possible to exceed the 125C Absolute Maximum junction temperature under certain very high load current conditions. Generally speaking when RL falls below about 25, it is important to calculate the maximum junction temperature (TJMAX ) for the application to determine if power supply voltages, load conditions, or package type need to be modified for the EL5191C to
